hi I wasn't sure if this was the right place to post this but I'm becoming desperate. Heres the story, my Windows XP has the latest AIM instant messenger on it, and for some strange reason it sometimes refuses to open the IM box for just my friend. Other people work, so I'm not sure if its because he's not updating his software or if it has to do with a Backdoor virus i just recently removed. Im pretty sure the virus didn't have anything to do with this since this has occurred several times before the virus showed. Please if anyone knows how i can fix this it would be a great help.
