I just recieved a payment sent me bitcoins on my old multibit 0.5.18 wallet. I opened it up and didn't see it, so I refreshed the blockchain. When I did this my wallet crashed. When I started it back up I got a message saying could not load the wallet. I went to the directory $HOME/MultiBit/multibit-data/wallet-unenc-backup to load a backup and got the same message.
Is their a way I can get the private keys out of the multibit.wallet file so I can build an unencrypted.key file. So I can send the bitcoins to my new Multibit HD wallet?
