Can’t Sign On in AIM, Only in AOL

Hi there-

I’m having a real big issue. I use pidgin as a 3rd party AIM client, and until about 2 hours ago it has worked perfectly. Suddenly, I open it up, and it can’t sign into my AOL/AIM account. The password has been rejected (it hasn’t changed since it last worked.) What is going on? Was I hacked?

I tried using AIM express, and that also rejected my password.

However, the interesting and puzzling thing is that when I sign on to my account with the AOL client, it works.
I’m using the same password with the AOL client as I normally use with AIM, and I’ve tried every password that I can think of.

What has happened? What’s going on?
