do i have to do anything from my computer when i want to play Xlink through xbox media center on my xbox? cuz when i go to xlink on my programs on my xbox, i can see what games are open and arenas and stuff, but then a few seconds later it says that i was disconnected from xlink. i dont have any firewall problems, as my xbox's internet connection is coming directly from the dsl modem. what should i do?
