I'm on Xbox live and I see that my friends are playing COD: BO but when I go to multiplayer->xbox live it has me sitting with a 'connecting...' image for a while and then it pops up:
The Call of Duty: Black Ops server is not available at this time. Please try again later or visit http://www.callofduty.com/blackops/status for updates. ( (A) Exit)
I've tried restarting my console, testing my xbox live connection (at first it told me my NAT protection was moderate and so I adjusted my settings by disabling my upnp and I inserted a static ip address and a list of forwarding ports and disabled filtering anonymous calls). I've tried just repeatedly logging in, I've tried signing in and out, rebooting my modem and router... nothing works and I don't understand what the problem is.
