You first need to run your wallet in server mode from the CMD window

Once the wallet opens you type brute.rb and then it will try to open another version of your wallet.

If you keep closing the windows error pop up it will try another version of your password and the error window will pop up again, rinse and repeat

I gave up after about 2 hours was far to slow and I wasn't even sure it was trying the passwords

I'm thinking of going with the wallet recovery service see if they have any luck, only problem is they charge 20% of your wallet
