Aim Problem

Well, aol in all it's glory has suddenly decided to not let me get online with my current screen name. I tried getting on an old name of mine and that worked fine but everytime I try my newest one i get "An error ocurred while trying to complete the connection to the host. Please try again." I get that the service is temporarily unavalible on my roommate's dell.
It was working fine earlier but when I got out of the shower I heard the error noise and that message popped up. The aim site was no help what so ever so I figured I'd come to you guys. Thanks in advance for the help.

Edit: Ok, well now it's working now but do you guys have any idea why it would do that?
