My friend and I used to play team doubles on Halo 3 all the time. Just recently, whenever we try to play, it finds people right away, and says "Player found", but then it says "restarting search". We thought maybe it was our NAT's, but we checked, and both of ours are open. We can play any other game type with each other in the same party. We can also both play doubles with any other person. I guess the prob;em is we cant connect to each other. But we both tried playing campaign online together (just us two) and it worked. So i don't know what the problem is. Someone please help? ):
