help plz

[TranquillityOfShyness]

i cant join my friend on cod but he can join and my NAT is open and so is his, it just started happening last night. i cant join his party or private chat

i have tested my connection and its fine, i can connect to COD fine, i can get into a lobby but when it starts and goes to the loading screen it stops half way/

i use wireless and i am unable to plug straight in.

my friend can join my party and join me but thats it.

any ideas on how to fix it? lol

Does CoD have a support site? Perhaps they may be able to help you since they know their system.... I dunno....
