Only things I can think of are:

MSN has a glitch they need to work out

Your webcam software needs some kinda update

Your internet has a hiccup (in which case don't try using honey lemon tea with it, the circuits don't like that). lol

Only other thing I can think of is possibly a virus or spyware causing a problem, in which case, make sure your antivirus and spybot software is up to date and run scans.

Otherwise I'm as baffled as you are. Good luck getting through the problem.
