I just got a friend of mine to buy F1 2012 so we could race co-op together, but now we're both unable to create sessions, or, if one of us manages to create a session, the other player can't connect. We've both made sure that exceptions are made in the Windows firewall, and we're pretty pissed that we're still unable to play this game together. Does anyone have any tips on how we can fix this problem?
