I'm not sure how this happens, but the wallet.dat file will not load in any version of Bitcoin-Qt. It just comes up corrupt. I tried to run PyWallet on it to recover it, but it just exists and doesn't spit any output out. (I am familiar with how to use it, as I used to to extract keys from a good wallet. Of course, suggestions are welcome regardless!) The wallet didn't have much in it, but I'd still like to have them accounted for. The sad thing is, I backed up this specific wallet both when I first created it, and when I had to reload my computer. The original one just .. vanished. I have no Earthly idea how that just happens, but the only copy I have. Is it possible to extract the keys using a hex editor? It was created using BitCoin-Qt 0.8.1 and I think I upgraded the client to 0.8.5, but I don't remember now.
