So I'm trying to log into my account on a different computer, because this computer is slow as hell. But I can't figure out whether I'm supposed to log in using my screen name or my e-mail address. So far both have failed, eve though I'm 100% sure I'm getting the password right. So what the heck am I doing wrong?

I just tried it again.

User name + password = works on this computer.

User name + password = "Invalid username or password" on other computer.

Never mind. Got one character wrong in password on other computer. Ugh.
