Hi, here is my problem:

I managed to play 3 games of black ops 2 before i got the error:
"ERROR: The Call Of Duty: Black Ops 2 Server is not available at this time. Please try again later or visit
Call of Duty: Black Ops 2 Status for updates."
on my main account (The servers weren't down my friends were all online).
I think i got banned or something because i dash boarded (signed out) during a game but they don't even have the decency to tell you your banned it just comes up with this error!
So i went on my other account and managed to play 2 days without getting this error.
But i got the error on my other account and now i get it on all my accounts that i go on even if i make a new account.
(this is not because the servers are down my friends are all playing BO2 Multi player when i get this error).
Please help me i just bought this brand new game and cant even play it
