Aim wont' connect using ICHAT

I have been using Ichat for my aim login. I have video chats often, but just recently Ichat won't connect to my aim account. I keep getting this message:


"YOU HAVE BEEN DISCONNECT FROM ICHAT SERVICES"
an internal error occurred that disconnected you from all ichat services. To resume using ichat log in again to your instant messaging account.

So, I tried creating a new aim account and that works fine. My gmail account also works fine. I have just noticed that I can't login to my old aim account using my ipod touch either. I thought maybe it might be an issue with aol, but i have been able to log on using aim express. Has anyone had this issue, if so, how can i fix this?????. Thanks.

 

What forum would you put it under. It is an issue on my macbook pro.

 

i tried changing it to 443, but it kept changing back to 5190. It won't let me change it. That also doesn't answer why the new sn i created works and my old one doesn't.
