MSN/ Big Problem???

Hey, I seem to be experience a lot of weird problems with MSN lately. For example, I would log on and then find that half (or more than half) of my list has gone disappeared. It`s not the biggest problem though cuz I can always reboot my computer and get my list back. The biggest problem is....I have been unable to LOG ON! Are you guys experiencing the same problem or it`s just me??
