For some reason I cannot access my wallet in MultiBit. If I try to send money, it seems not to accept my password, stating "could not decrypt bytes". I set a password on my new wallet right after I created it, thus unfortunately I don't have an unencrypted backup of it.

There is a very minimal change of misspelling it twice. I made a macro that tried to bruteforce about 10k variations of that pass, but without success. The other two wallets I created using the same password work well.

Is there any change the encryption could have been corrupted somehow? Is there any change of accessing my wallet? I guess the password protected exported private key won't help me.
