Lately I've been going online and playing a couple games of black ops 2 but like 30-45 mins in game or just online I get signed off with 2 error codes; 8002ad23 and 8002a548. It's really bugging me, does anyone have info on this or anyone have the same issue. Please help. It also signs me off when I'm not even playing, I sign in and 30 mins later or so it signs me off. Help.
