Okay, so here's the deal

When I sign-in onto MSN, my MSN freezes right after and it doesn't respond. I've tried re-installing, but nothing works! I've tried using 7.5, 7, and 6.2, but all of them have the same problem... my MSN just freezes after sign-in

For Windows Live, it's a little bit different. I start it up, but the icon in the system tray doesn't show up, and I go to the task manager, and it shows that it's running, but the MSN Live doesn't appear. So yah, that's even worse... I can't even see it!

Currently I'm forced to use Trillian... does anybody know what I could do to fix these MSN problems?
