contact them they will give you the password

First of all when you set up your password originally did you put in a password Hint? If so, if you type an incorrect password 3 times trying to log in it will show you your hint. I recommend trying this. You might find you have a hint which will help you remember! If not:
You can reset your administrator password by inserting your MAC OS X Install Disc 1. Then Restart your computor and hold down the C key as it starts up. 2) Choose Utilities>Reset Password from the menu bar and follow the onscreen instructions there. I know of no other ways to get back your password. If this is helpful, please vote or comment! Good luck!
