Pywallet works.
Download it ->
https://github.com/jackjack-jj/pywalletDump wallet with command -> pywallet.py --dumpwallet --datadir=C:\Users\******\AppData\Roaming\Rubycoin_v2\ > dump.txt
You should be able to run this command in Command Prompt (Start command prompt with CMD).
This will dump all your private keys to a text file and you should be able to read them from there. You can import your private keys into a new wallet.
Remember to backup your old wallet first.
