You managed to corrupt parts of it somehow. Make a backup (before doing anything else) and try starting with -salvagewallet that should put your private keys in a new wallet dat and rebuild the transactions etc
To do that just open run menu (win+r) and enter (assuming you have 64bit windows, otherwise remove "(x86)"
i have no clue how to get there
To the left of the spacebar onyour keyboard is a Windows logo button. Hold that down and the letter R key at the same time and then let go. A box will open that says "Run" and then copy/paste this in the box
c:\program files (x86)\Guerillacoin\guerillacoin-qt.exe -salvagewallet
Then press enter.
thx i tried it but my balance was 0.00 bout to go primate on my pc lol
Don't panic, it will be ok. What you need to do next is rescan your wallet:
Assuming you mean WINDOWS 7 you:
1) Create a shortcut for guerillacoin-qt.exe on your desktop.
2) Right-click the shortcut and select properties.
3) In the field labeled Target type -rescan on the end.
P.S. default is "C:\Program Files (x86)\Guerillacoin\guerillacoin-qt.exe" so the target field would end up looking like
"C:\Program Files (x86)\Guerillacoin\guerillacoin-qt.exe" -rescan
Thank you i tried it didnt work i only lost 300 coins but still
