A problem with AOL??? whAATTT??? haha jk, do a little trouble shooting, i know for a fact that tv tuners themselves are very very touchy, just because it is such a hardware orientated technology, but try some things, watch what aim and your tv tuner does in the windows task manager when you do what you do. And one more thing, try trillian, its another messenger service that can host aim, windows messenger, yahoo messenger, or any other messenger you could want to use, at least try it to see if its aol's software or the actual connection.
EDIT: BTw, all the messengers that you host, are all in the same window with trillian, no seperate interfaces!!
