After playing for about 5 hours with my friends, I get disconnected with a error 3007. I can't log back on because I either get a error 37 (servers are busy at this time), error 3003 (unable to connect to the service or the connection was interrupted) or error 75 (There is a temporary outage of the battle.net service). I've tried restarting my game and computer several times with no change. What is going on?
