NXT :: descendant of Bitcoin - Updated Information

[kwest]

I had the rollback problem as well. Deleted and unzipped a new copy of 0.3.14. Ran it and everything is good.

me too 

Me three. Man, what an exciting night for a nerd like me. Wild swings in Bitcoin, negative values in Nxt.
Oh, crypto currencies, how I love thee.

help me I am in process of starting a trade and I cannot access my account

[Sparky_eMunie]

Java is a pain on the Mac. eMunie has also a lot of problems running on MACOS X. Basically Java is for Windows and Linux.

[lophie]

where are you getting these super uper new versions? I need 15!

[Sparky_eMunie]

I think download link is always the same:

The download link is always the same.  New versions are uploaded over the old versions.

Can somebody knowing how NXT works reply to this?

See that first message?  It says that port 7874 is already in use on your machine.  This could mean:
- some other software on your computer is using that port
- you're already running the software once and java is trying to start another instance

Try rebooting to get your Mac into a fresh state, and try again.

Also, what java version are you running?  Execute this command:

java -version

...and take a look at the output.  Nxt requires Java version 1.7.  If you have anything older, go to http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html, where you can download the updated JDK (you want the "Java SE Development Kit" download!)

Stop your software.  Then, in your nxt folder, delete all your .nxt files and replace them with their cooresponding .nxt.bak files:

- delete accounts.nxt
- delete blocks.nxt
- delete transactions.nxt
- rename accounts.nxt.bak to accounts.nxt
- rename blocks.nxt.bak to blocks.nxt
- rename transactions.nxt.bak to transactions.nxt

Restart your software and check your client.  Let it "catch up" with the blockchain and see if your issue is resolved.

If NOT, you can always do the "brute-force" approach: stop the software, delete the nxt folder completely, and download a fresh installation of Nxt.  Your account will be fine -- it's in the "brain" and not on your computer.

Thank you! That solved the issue


I'd also like to ask you one more thing, since you seem to know a lot about NeXT: should I just leave it open to be able to mine? I purchased 100K coins.

BTW the newset block that my client sees is #8689

Well, I can answer that. You need to unlock your account and wait 1440 blocks since the first transaction into the account. Once that period if over, if everything is working correctly, you'll see "X hours Y minutes till next block". That's your mining timer. It'll reset every new block. You'll get it when you see it.

Once you unlocked your account, if you want, you can close the webpage, but leave the java applet running in the background to continue mining.

Also, just to make sure, do you have a 30+ char password? (That's not prone to dictionary attacks) Been seeing a lot of people losing their NXT due to weak pass-phrases.

[jackyrozario]

localhost/7875    does not connect ,so I deleted the *.nxt files and rename *.bak to *.nxt.   but stll the same ,

I am Running 0.3.14 with newest JRE on W8.

I have a very strong password, thanks.

Thank you also for the tip of closing the web page, while leaving the applet running. Is it worth mining at all (I have 100K NXT)? Or should I have had more coins?
