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?

Many thanks

Unlike traditional banking where clients have only a few account numbers, with Bitcoin people can create an unlimited number of accounts (addresses). This can be used to easily track payments, and it improves anonymity.

Can you check the logs, and send us anything containing the keywords "Exception", "Panic", "Die", "Exit", or anything else relating to programing exceptions.

Not sure if you were trying to be helpful or funny, but you were neither. Again, I need to be able to load up my 0.4 wallet.dat file to 0.5, and it won't do it. If someone has an idea, please let me know.

Edit: found a fix. Got an old computer with an old version of the client. Uploaded wallet to it, then installed v0.5 on top of it.

Well, I was trying to be helpful, and if you were to find those in the logs, you could find the name of the exception, then you could find the cause, and that would be very useful.
