1.you enter there username and then click the + sign
2.then goto the password and enter the password you think it is. Then click the + sign
3.then click start cracker
4.then goto the logs tab and it will tell you if you got it wrong or right. If you got it wrong nothing will be there, if you got it right it will say there username and password (ex. username:password )

There is a 1 in Million chance you will actually guess there password right. But good luck. I've only gotten a few out of the cracker. You can enter more than one password at a time, just be sure that everytime you enter a password click the + sign.
