Well i just tried to get into co-op and got a loading screen and no further.. And the music started some two to three mins after the screen loaded... Real shame was looking forward to it this evening..
Running an custom water cooled i7 sli with all the trimmings, Not that will make much difference As myself and a friend got exactly the same.. we were running skype to chat not sure if that will affect anything.. So i know it`s not just me!!
And yes my friend and I did re-load the game twice.. same result, So not sure if anyone else had the same issue.. did not try pvp but in global chat most have said that was ok!!
