Hi all, sorry if this has already been addressed. I upgraded to version 0.4 when it came out a few months ago. I then saved my wallet.dat file onto an external drive.
Today, after downloading v0.5, I tried as usual to just copy the wallet.dat file into the appdata/roaming/bitcoin folder, but when I try to start up the client, it crashes.
If I let it start up with its own wallet.dat, it runs perfectly, downloads the blockchain and everything... but then my wallet is empty, which isn't good :-)
Aside from trying the same trick on another computer hopefully running v0.4, is there a known issue with trying to start up v0.5 with a v0.4 wallet.dat? How do I fix it?
Can you check the logs, and send us anything containing the keywords "Exception", "Panic", "Die", "Exit", or anything else relating to programing exceptions.
