Wallet.dat

[couchinator]

So I reinstalled Windows the other day and transferred my wallet.dat file from my old install to my new one. I placed it into the AppData\Roaming\Bitcoin directory and now Bitcoin crashes when I try to start it up. There are no other files in the folder, although new copies of the rest of the files are generated when I start Bitcoin. I don't see how anything could have happened to the file. There seem to be many other people with a similar problem but I haven't found any answers. I can't figure out how to use the Berkeley DB tools to get the file fixed. Does anyone have any insight as to why the file might just stop working?

Thanks

Try running with the -rescan flag. From the command prompt, in the directory containing Bitcoin, run "bitcoin.exe -rescan"

Tried that, still crashes

Does debug.log say anything about it?

[couchinator]

Nope.

That's where it ends. It's very annoying to have BTC in the file somewhere but I just can't get to it

Does Bitcoin actually die, or does it just hang?

Did you change Bitcoin versions?

[couchinator]

It dies. I have tried the new version as well as the older version (0.3.20.2) that the file was created with. No dice.

Did you reinstall from 64 bit to 32 bit or 32 to 64 bit?

[couchinator]

Both installs were 64.

[couchinator]

Alright, I have read elsewhere that Bitcointools can help, so I tried that as well.

./dbdump.py --wallet

Also not helpful.
