Help "untrap" my btc

[platinumsteel2016]

Periodically my desktop wallet says " Obsolete. Upgrade". My Qt Client version is 4.8.3   My wallet ran an "indexing" process on its
own recently. But the upgrade message still shows periodically.

Just recently I ran two transactions. I sent some btc to my blockchain online wallet, immediately, I third to send a 3rd transaction.
It showed in the "sent" section that it was sent, but it never arrived to my blockchain wallet. Blockchain said that I still have my btc even though my desktop wallet says that it was sent. I don't know what to do to undo or fix this problem...This a copy/paste of the transaction

Is it a matter of upgrading my Qt???  Under the help tab in my desktop wallet it states "Qt is a Nokia product. See qt.nokia.com for more
information." I can't find the site.  Please help retrieive my btc (Please explain in layman terms)...I hope to hear from you very SOON!!!

I think you are getting confused. QT is not the same thing as Bitcoin-qt. There is no version 4.8.3 of Bitcoin Core (formerly known as bitcoin-qt). Qt is a library made by Nokia that bitcoin core uses and comes bundled with and its version is 4.8.3. you need to upgrade to the latest version of bitcoin Core, which is 0.11.2. you can download it here https://bitcoin.org/en/download

Qt is just the part of the software that shows the things on screen. The version of qt is not as important as the version of bitcoin core/qt you are running. I suspect your version is old based on the message. Probably pre 0.9.x.

Old versions create transaction in a slighly different way than the latest versions, this helped reduce the impact of a spam attack on the network. In order to avoid this problem you should update your client. The latest version can be found here -> https://bitcoin.org/en/download

HI,

Thank you for the much appreciated information on the forum "Untrapping my btc". But I have encountered another
problem I sincerely hope that you can help. Just recently I took my computer in for service, because for a week it
wouldn't allow me to connect to the internet...So the serviceman ran various virus and maleware sweeps.

He  told me that he found and removed 1644 .  I also noticed that my desktop wallet icon was missing. I immediately
checked the "add remove programs" section it showed the it is still listed. I don't understand what could have happened to the icon. This happened before I had the chance to download the latest qt from the link that you
provided...I remembered to backup the wallet.dat file so is my btc within that file, and by downloading from the link
you provided will that create a new wallet, and by me having the wallet.dat file will from link automatic configurate
itself  i.e will open will same passphrase, or what should I do at this point... I hope to hear from you SOON!!!

as long as the wallet.dat is still in place (it should as long as your service man did not delete it) it will work with the old passphrase.
if he just removed the bitcoin app from your system you are all fine.

if he deleted the folder %APPDATA%/bitcoin you have a problem though - and i hope you have a backup (if not please make a backup of the file called wallet.dat in there NOW)

[cr1776]

Beware if he removed 1644, someone could have copies of your private keys.  Your service guy could have copied your wallet, and a virus could have.  1644 doesn't do that in the variants of which I am aware, but there could have been others or it could be a different variant.

So, if it were me, I'd move my coins to be safe.  Even if your service guy is honest, there could've been other people around who were not.

UPdate:

As we speak, the latest core is running the index process. I can see btcs pending. I also see in the "sent" section the btc that didn't make it over to my
blockchain online wallet. Once the new core finishes updating will it automatically put the btcs that are "trapped", back in my desktop wallet, in essence
will this new core configure everything on its own. I may have a copy of a backup on my computer, but I backed up the LATEST backup before this problem
happened, and I saved it on a flash drive. I do intend to move my btc to my blockchain online wallet then get a new computer.  I just want to retrieve my btc
on my desktop wallet first...I would like to hear from you (soon).

Bitcoin network needs 3 confirmation, when its done. I recommend http://www.coinmotion.com/

I need help again...I downloaded and ran the new Qt. (almost 2 weeks of running), it
gets down to 19 weeks. When I awoke the next day. I see an error message that says:
"fail to connect best block" , then another message that said "Error: A Fatal internal
error occured see debug lg for details". WTF happened?

I have my wallet.dat file saved on a flash drive from my original wallet. My passphase is
also saved on my flash drive. I tried to run the programs 4 or 5 times, then I immediately
downloaded another version (I didn't delete the old one). I ran the version just downloaded
and I received the SAME error message. What do I do now. If the program wont open
how can I get to the debug log. I wouldn't know what to do once I got there. Please help
me....(layman terms p-l-e-a-s-e). I hope to hear from you very soon!!!!

Go to the data directory (os specific instructions here: https://en.bitcoin.it/wiki/Data_directory). Find the debug.log file. Post the contents here.

[platinumsteel2016]

I tried to paste the contents of the debug.log file, and I received an error message when I click post:
413 Request Entity too Large.
What do I do now???

Paste the stuff from the last run. Scroll up from the bottom of the file until you reach a section with a lot of empty lines. Copy everything from that area down and paste that here.

So it looks like you have a corrupted block on your disk. You can delete blk00333.dat file which is causing the problems but doing so would require having to reindex again, and from it looks like, it will take you a really long time.

Another option, which would probably be faster for you, is to download someone else's fully indexed data directory. This thread: https://bitcointalk.org/index.php?topic=1310261.0 links to one that is fully indexed and ready to go, you just need to download and unzip the file. However, do so with care as I don't think it has been verified to be trusted yet (although it is probably safe to trust it). It is downloaded as a torrent.

[platinumsteel2016]

OK...But how do I locate the blk00333.dat file to delete it ?? I'd rather be safe than sorry.
Is there any particular way I should delete it???

I hope to hear from you very soon.

That file is located in the blocks folder in the data directory

[platinumsteel2016]

I TRULY appreciate your time and PATIENCE!!!

How do I locate the data directory?? From what you said, once I get to the data directory I will click on the folder and search for the block folder.
Once there I will click that folder and then proceed to find the blk00333.dat file then delete it...Am I correct in this procedure?? If so, all I will need
to know is HOW to get to/locate the data directory...I hope to hear from you very SOON!!!

Assuming that you have Windows and did not change the default directory, your Blocks folder should be located in %appdata%/Bitcoin. You can then see the blocks folder and find the file.

However, with the blocks deleted, Bitcoin Core will need to reindex the entire blockchain. It can take sometime for Bitcoin Core to verify all the blocks depending on your CPU and Harddisk speed. You just need to let it reindex.

[platinumsteel2016]

Update:

My wallet is reindexing as we speak...So I guess I'm making some progress.
I will be overjoyed when I can finally get my trapped btc back. I know how to
show my appreciation via donation.

I will keep you updated. The indexing will most likely take 2 weeks.

What sort os system are you running, it must be pretty old?  downloading the block chain should really only take a few days.
