Now I've ran into a new problem which happens with both the new and the old version of pywallet. Sometimes it scannes the "recovered-wallet.dat" file, and actually tries to recover the keys to a new files, but most of the times it just skips everything without an error message:
Read 2.1 Go in 0.6 minutes
Found 0 possible wallets
Found 0 possible encrypted keys
Found 490 possible unencrypted keys
All the found encrypted private keys have been decrypted.
The wallet is encrypted and the passphrase is correct
Importing:
The new wallet H:\recover/recovered_wallet_1384452226.dat contains the 0 recove
red key
C:\Users\Name\AppData\Roaming\Bitcoin>
Any idea? Am I doing something wrong?
