How to recover password by truecrypt

Hey guys,

unfortunately I forgot my password by truecrypt. I know it was a simple one but all my tries weren´t succsessful. Shortly I read oclHashcat-plus would be the best tool to solve this problem. I tried to look how to do that but I still unsure about the procedure.

Can anyone help me or refer to a link for tutorial? Is oclHashcat-plus really the right tool for mu issue?
