Hello my name is Cameron, and I have been trying to figure out how to get COD4MW2 Multiplayer to work for a while now. I'm now using Crossover with the Steam client...I can get Single Player to work fine, and Multiplayer opens but when I click "PLAY" it says "Must be logged in Steam in Online Mode to Play." I'm logged in to Steam, and that's where I opened the game from...I was just wondering if anyone had any ideas about this issue I'm having. Thank you!
