Can't join Modern Warfare 2 game online

Tried everything...I didn't have a problem with it the other day, and now it just endlessly searches for games no matter what mode I select. My NAT is open, all TCP and UDP ports for the game are forwarded that were listed on portforward.com, uPnP is enabled, etc. etc. etc. Anyone know how to remedy this problem?

Thats odd Im playing as we speak with no problems.

bump.

how have you been waiting after picikng the gametype? because in mw2 joining game is a little bit longer than cod4
