When I launch AIM, it goes as far as loading buddies, but I cant past that.
I deleted the prrogram and rre-installed it, but no help.Any thoughts?

AIM on the 71xx series is horrid. That's probably a limitation of the small internal memory in this series of Blackberrys. It can take forever to connect, and if/when it does it's likely to drop the connection at any time. I have found it generally worthless.
