Oh I see. My syster does the same thing with her passwords. She saves it as auto-logon and forgets her password when she needs it.
So you forgot the password to your e-mail address too, I'm guessing. If it's an ISP e-mail address, e.g.: AOL, I think you can call them, then they can reset your e-mail/user ID password. I'm not sure exactly how they do it though.
