Me and a friend are trying to play Multiplayer but we are unable to invite one another to the lobby. We are both running Windows 7, using the non-steam version, and are able to connect to public games. According to Bulletstorm both of our NAT's are open and able to host games. Is there any recurring problem and corresponding fix for this issue. I thank you for your time and help in advance.
(I am aware there was a thread on the PC forum with a similar issue, however it was full of some very far off guesses as to the issue.)
