My son rented GoW3 a few times over the last few months and recently bought the game. He used to play online without any troubles. Now when he starts up the game any option to play multiplayer. And if he tries it tells him he needs to be set up to play online or something to that effect. Sorry I can not be any more specific at the moment as my son is asleep.
I did write to epic and was told he is not on the ban list. Also spoke with xbox support and tried everything they recommended.
As I can not supply any more info right now I was wondering if you could suggest possible reasons from what I have said.
Thankyou for your time.
