msn piss off!!

While I'm in class I decide to sign into msn because I'm on break and I need to entertain myself some how. I do my normal thing but I MUST update msn or I can't log in. Fine I do this but I don't check mark anything. Now I can't get onto the internet. Google won't load with my firefox. Of course this window was open before, so I can write on here. But this is honestly very very frustrating!!!
