You probably don't have the latest patch, go to properties, updates, and the select "maintain this game updated", then it should work.

is the latest patch 1.7 ?

i have the same problem ^^

Go to steam,open your game librarly,right click on mw3 multiplayer then properties then local files then verify integrity of game cache.After its done you should have a a update after that mw3 will work.Try it now and give me feedback

Yeah, this happened to me too. I swear if they don't fix the "servers" then I'm not going to play this game anymore. Just battlefield. This is crazy how they haven't fixed it yet. It's been happening to me for the past 2 weeks. It's totally unprofessional. I'm sure the headquarters can read our comments, but have done nothing yet.

its been doing that to me telling me to go http://www.callofduty.com/mw3/status/for updates i updates my ps3 and mw3 then i get online to play with my friends i play about 3 games with them then i get kick out and get singout i am not that happy when is happen 2 me with the game mw3 got the new maps so i can play them
