2. Uninstall Electrum from Add/Remove Programs in Windows 7
3. Go to C:\users\username\appdata\roaming\Electrum and remove electrum.dat file

he said he had already uninstall/installed electrum
and also there is no such file called electrum.dat in that location! are you by any chance copying these steps from an old topic about version 1.8?

i also hope OP could have provided more information about this problem, although i have never had this problem myself i have seen a couple of others having the same issue but they never stay around to fix it! we never find out if it was really a problem with electrum or they were doing something wrong.

Yeah, if there is indeed an issue with Electrum on some PCs from initial installation, it would be great to be able to isolate the bugs so they can be patched.

I've seen several similar reports from new users but not sure what would be causing this.
902  Bitcoin / Development & Technical Discussion / Re: Bitcoin Core 0.14.0 release candidate 1 available on: February 20, 2017, 05:01:27 AM
The release notes are still a bit in flux.

There are some really nice performance improvements in 0.14 which aren't mentioned in the release notes yet.

Another major feature in 0.14 is support for after the fact fee bumping-- if a transaction is taking longer to confirm than you want, you can increase the fee.

The release notes make it sound like getinfo is gone completely. This isn't the case, it has been marked deprecated and will be phased out in the future. But for now the only change is that the help for it tells you not to use it anymore.


Nice. I'm assuming the fee bumping is utilizing RBF to accomplish this and just providing an interface to make the process easy for users?
903  Economy / Exchanges / Re: Is Coinbase.com Reliable? on: February 19, 2017, 06:13:47 AM
Yeah, they seem to be fairly restrictive and have been known to freeze accounts before. They are definitely anti-gambling so you don't want to send to any gambling websites from their wallet.

If you follow their rules, I suppose you will be fine though.
904  Other / Beginners & Help / Re: Speed of transaction on: February 19, 2017, 06:10:59 AM
Was waiting on a blockchain transfer yesterday on a site with a active chatter box and got frustrated waiting for multiple hours. So in chat someone told me to use --------- site instead of blockchain and it would be faster.
I thought all transactions had to go through the blockchain and would only be sped up based on fee, so what am I missing?
Was this just pulling my chain or are there ways to bypass the blockchain?

Thanks for clarifying..

Depends on if you are talking about the blockchain or blockchain.info the online wallet.

All transactions are on the blockchain and the only thing that speeds up a transaction is including a larger fee so that your transaction has priority. The wallet you to send the funds won't change the speed that the transaction confirms in itself
905  Bitcoin / Electrum / Re: Low fee issue on: February 19, 2017, 06:04:13 AM
It looks like I can't. TXN accelerator gives this error.

Yeah, the accelerator only works for transactions that have a minimum of 0.0001BTC/KB fee.

Checking on the transaction and it looks like it did confirm already which is a good thing. Perhaps it was due to messaging those users.
906  Bitcoin / Hardware wallets / Re: Best Hardware Wallet on: February 19, 2017, 06:00:21 AM
Hello everyone,

What would happen if I had some bitcoins in a Nano S wallet and someday ledger decides to drop the project. Would I be able to still use my wallet somehow if I had my seed?

Yes you can import it in a wallet which is compatible with that seed. I know electrum is, so you can restore your wallet through your seed in Electrum which supports BIP32 and BIP39. I am not sure but even Mycellium supports this, so yes there are a few options.

And even if ledger decided to drop the project, the current Nano S wallet should still function fine when using a client such as Electrum or the other existing wallets that support. I'd imagine their own App would function as well, you just wouldn't receive any new updates.

Quite an impressive profit he has there and that 8 btc win in a single game was quite the hit as well.
908  Bitcoin / Electrum / Re: Low fee issue on: February 18, 2017, 05:53:09 AM
I've made a mistake while trying a test transaction (small amount). The fee that I've manually specified is apparently too small and the transaction is not being confirmed. I'm getting this error in Electrum wallet. Transaction id# 2fdf9644b29984e9fb707e3a473de022d1b6d6e1249c7cf948525c58b9d7f571



I don't see a way to abort this transaction and retry with a better fee. Just wondering how to get this transaction confirmed  Huh


Unless you have the Replace-By-Fee (RBF) feature enabled, I don't believe you can retry this transaction until it falls off on its own or confirms.

You may be able to restore your seed into a new wallet where the transaction doesn't exist and douplespend it be able to send a transaction with a proper amount of fees though.

RBF wasn't enabled. I've enabled  it just now. Not sure if that's going to make any difference though.

I've tried doublespending, but it looks like the new transaction didn't go through either.
Transaction id# e553cd00e2130deb7151455975a71a97b6d49c412eb030d0af9e5c8b848f85a0

Maybe, I didn't perform this step right  Cry

Your new transaction included very very low fees as well. You only included  5.2 sat/byte in fees when the network wants about 140 satoshis/byte right now.

I'd strongly recommend using the "Dynamic Fees" option within Electrum preferences. This will give you a slider to control confirmation speed based on fee size and better estimates accurate fees for transaction to help avoid these issues.
909  Bitcoin / Development & Technical Discussion / Re: Fake Transactions on Blockchain.info on: February 18, 2017, 05:49:42 AM
Are they non-standard, or invalid (until if/when SegWit is activated)?

IIRC, amaclin had claimed to get BC.I to display a SegWit transaction that was "from" an address whose private key he did not control/have possession of.
They are non-standard because old nodes will still accept segwit transactions if they are included in a block.

So why does BC.I accept this transaction while almost all other nodes reject it? Are they running an older/newer node or something?

Other nodes give errors such as "Error sending transaction: Error running script for input 0 referencing 725c1a127e66c6e9ebc97ef065d5fff8cb43234651ef4e1fe5eec29175ff28e7 at 1: Script was NOT verified successfully.." when attempting to push this TX.
910  Bitcoin / Development & Technical Discussion / Fake Transactions on Blockchain.info on: February 17, 2017, 10:01:30 PM
Does anyone know how this transaction and string of transactions is showing up on Blockchain.info when they don't exist on the network?

https://blockchain.info/tx/cbe60842c6b0d98042c680ffff172db55fe5ad48ac90c31ed61bd4e30ce1eb51

Is this some bug with multisig transactions that makes blockchain.info think the transactions is legitimate? I tried decoding the transaction but I don't know enough about raw transactions to further investigate the actual cause.

There is a scammer going around that is able to make fake transactions appear on blockchain and is using it to attempt to scam people by making them think he made a payment to them.

912  Bitcoin / Electrum / Re: Electrum wallet wont open win7 on: February 17, 2017, 04:16:47 PM
Hi,
I have the exact same problem under Windows 7. As I mentioned in some other thread here:

btw I just installed Electrum, I created a standard wallet, got back a 'seed' to store on paper and then... nothing. Electrum won't start.

I un-installed it and re-installed it and still, when clicking on it, it kind of starts, I see for a second the task icon on my task bar, and then it's gone. This under Windows 7 with the standard installator. I'm not getting a security feeling about all this.

Is it a known problem?

What version are you running? The latest is 2.7.18 so make sure you are using that if you aren't.

Did you try removing the config file as shown above to see if that resolves the issue?
913  Economy / Gambling / Re: BITDICE CASINO - CONGRATULATIONS TO WONTON FOR WINNING 300BTC on: February 17, 2017, 02:52:52 PM
Yes, I do agree with you that the dice site with have much higher maximum win stands to attract bigger whales because of the martingale strategy, the higher the maximum win is allowed in a casino, the more times a user can double their bet amount resulting in high crazy wins amount if he get really lucky.

Bitdice does looks like a good site to invest with the number of active high rollers rolling on their site, investor might get some great profit if the high rollers get a bad red streak.

Yeah, and the site has already seen some bad red streaks recently. It is nice to have the high max win though to give the freedom for user's to make large bets and not be restricted by the site's maximum win value.
914  Bitcoin / Electrum / Re: Electrum wallet wont open win7 on: February 16, 2017, 08:37:36 PM
Hi I installed the electrum wallet about a week ago (dont know version number) last night everything was working fine but today I have tried to open the wallet and nothing happened I tried as run as admin still nothing I have got the seed wrote down, should I delete the wallet and create a new one from seed or is there another way to open it?  Huh

I would double check in Task Mananger to make sure there isn't one already running and kill it otherwise. Restarting Windows is also an option if you haven't done that yet.

If you are still unable to open it, I would try removing the config file from your User directory which should be located at
Code:
C:\Users\USERNAME\AppData\Roaming\Electrum\config

Try this and then restart it and see if it loads.
915  Bitcoin / Electrum / Re: Strange thing happening. Can't send BTC on: February 16, 2017, 03:16:55 PM
I see that you are using an outdated version of Electrum ( 2.7.11 ). Can you try updating to version 2.7.18 which is the latest release and see if your issues persist?
916  Bitcoin / Electrum / Re: My Electrum client doesn't start any longer under OSX on: February 16, 2017, 03:15:07 PM
Try backing up the ".electrum" folder within your user profile and then deleting or moving it which would force Electrum to recreate the folder. If there is something in your profile that is causing the issue, this should fix it I believe.

thanks for your help.
maybe next time you could suggest to delete only the .electrum/config file, so the user keep their wallet data.

Thanks for the info. Yeah, in the future, I'll suggest that they only delete the config file first to see if that resolve the issue that to avoid having to recreate the wallet and resync.
917  Bitcoin / Electrum / Re: Problem with Electrum-DASH 2.4.1 on: February 16, 2017, 03:12:38 PM
I have a big problem with Electrum-DASH 2.4.1.

Can't send transactions because it shows an error: "Your client produced a transaction that is not accepted by the network any more. Please upgrade to Electrum 2.5.1 or newer".

But I can't find Electrum-DASH 2.5.1 version...

Need urgen help guys Sad

Unfortunately, I believe this board is only for the official Bitcoin version of Electrum.

It does seem that Electrum-Dash latest version is 2.4.1 so this error message is prob actually due to reused code from the original Electrum. I'd recommend that you contact the authors of Electrum-Dash and possibly open up a bug report on their github in order to further investigate your issue.
918  Bitcoin / Electrum / Re: Transaction rejected on: February 15, 2017, 08:58:36 PM
And use the "Dynamic Fees" option within preferences so you don't have to worry about calculating the correct fees yourself. Its a great feature!
919  Other / Beginners & Help / Re: bitcoins and mining on: February 15, 2017, 02:57:28 PM
Nowadays, mining won't really be profitable unless you have access to cheap/free electricity and live in a cool climate where you aren't spending a ton on cooling or you are using your miners to generate heat instead of using a heater   Tongue

If you do plan to mine though, I'd recommend only doing so with a dedicated ASIC hardware miner as they are quite a bit better at mining than any other type of hardware.
920  Bitcoin / Bitcoin Discussion / Re: Would you still use Bitcoin if price would be stable for years? on: February 15, 2017, 06:39:58 AM
Would I be willing to sell items for it? Sure. Would I buy and stack it? No, I would use it to buy stocks that have a dividend, I think a lot of us here are interested in increasing our wealth, for first world nations our fiat works well. I don't need another currency, I want something better, and staying at 900 USD for 50 years means it loses buying power just like the dollar.

I agree with most of these points but I also think that Bitcoin is a great currency and provides an easy of use for purchasing goods and services securely. I'd still use it for purchasing and selling items, but if its entirely stable there would be no sense on holding onto it for long periods of time as an investment.
