I haven't been able to go on my msn messenger for months because my computer has somehow disabled it Along with all of the other chat rooms! We don't have a firewall or anything

Whenever I try and get into msn, it starts to work, but suddenly the page freezes (the other pages don't freeze) And it will say that the program is not respnoding

Does anyone know how I might be able to fix it???

It would be neat to be able to chat with some pet talkers lol
