Hello!
My wallet started not updating the blockchain after some error occured making it stop responding. I'm getting afraid my bitcoins are in danger, I've tried re-installing it, but the same problem occurs.. Any ideas?
Right now instead of the update progress bar it says "Displayed transactions may not be correct! You may need to upgrade, or other nodes may need to upgrade"..
if you are using the basic client
1) locate a file named wallet.dat it should be in something like "C:\Users\admin\AppData\Roaming\Bitcoin" and copy it to a safe and private location.
2) Uninstall the bitcoin software
3) delete the bitcoin folder at "C:\Users\admin\AppData\Roaming\Bitcoin"
4) reinstall the software.
5) Start the reinstalled software and let it run for a couple minutes then close the software.
6) Navigate to that same folder "C:\Users\admin\AppData\Roaming\Bitcoin" locate the new wallet.dat file and replace it with the old wallet.dat that you copied earlier.
7) Run the software and wait for the blockchain to update and it should be as good as new.
