i've got everything setup, verified with all the checks, and have successfully played games in the public multiplayer rooms, but for some reason in the 'Zombiez' public room, no matter what i try and even with 9-10 users in the room, i can't get games to show up on the systemlink list. i've seen 1 pop up by random every now and then as it to play with my eagerness to play but it would just hang upon joining and tell me that it couldnt connect or something like that. i did play a zombies match in a users created room but never was i able to get a public one going. any info is appreciated thanks.
