Thanks Stinger. I've verified that AI Traffic is on (Sliders at 100%), I've also tried live multiplayer as well, no dice. In the top menu, the control tower icon doesn't even show up! First one is the camera, I don't see the tower. It's very strange. Also of note, is in the top menu, if I go under options, ATC is turned off and grayed out. I cannot turn it on!!! I've even gone to the extreme of deleting the entire game and redownloading/installing! Nothing works!
