I've been having issues connecting to the servers. It used to work fine once I got it then about 10-20min after I got it I exited zombies which had previously been working fine (multiplayer worked fine too) and I tried to reopen it, everything was normal until I clicked on online, the load time was much longer than usual. Then after like 3 min of waiting it says the "The Black Ops 2 servers are not available" I've tried everything but can't get it to work anymore. Can someone help me, please.
