so i have played alot of mnc over the past 2 days. suddenly i cannot connect to any games it just says searching forever. now i have been using a moderate NAT for a few month's since it changed itself. i encountered no problems until now. so i went and figured out how to open my NAT and did so. when i use matchmaking it starts a lobby and like 3-5 people can join but thats it. i also cannot play any other games online. i used this to open it http://answers.yahoo.com/question/index ... 550AABB6Hx it worked my NAT reads open, my UPNP is enabled, and when i test my connection on my xbox it says everything is go for launch. anyone know what i can do? thanks
