More than likely his wallet is on a forked chain. He needs to follow what the devs said to do to remedy it. I did it and havent had any problems, yet.
Ok, I think I found where the devs give directions to fixing the wallet. Do I need to re-download the block chain again? Its not a problem if I do I just want to make sure I am doing this right. So from my understanding I edit wallet config file and download block chain, place block chain in proper place, then open wallet. Does this sound correct?
