Step 1: Get someone to send you there .minecraft. What I do is befriend people then make a new text document named minecraft.jar send it to them and say its a client. Tell them some people have told you it won't load(obviously it doesn't since the files empty) and that it worked for you. Once they say it didn't work tell them to send you their .minecraft so that you can try and see why it's not working.
Step 2: Take the file lastlogin from their .minecraft folder and place it in your .minecraft.
Step 3: Open the file LLD.jar, and if the person selected minecraft to remember their password, then it will display their username and password.
Step 4: Enjoy your new account!
