login in problem

Hi! I’m new to the forum, and am SO glad I found it! My question is about a friend’s computer that I was working on. We downloaded the latest version of AIM. All works well EXCEPT……………………each time we boot up the computer, AIM connects as it is supposed to, but there is always a login error (sorry, I didn’t write it down and she lives in another town). However, after that happens, if I go to her buddy list and log in through it, it logs in fine. Any suggestions as to what is causing it to only log in manually and not automatically? It’s a new emachine with Windows XP, Zone Alarm free edition firewall, and AVG free version antivirus. Thanks so much!
