Whenever I try to play a multiplayer battle on Rome Total War, It says I have an invalid CD Key. I've tried to re-enter my CD key in the "New Cd Key Slot" and now whenever I click on "online battle" in the multiplayer section of Rome Total War it seems to be working but the game freezes. Does anyone have this same problem or can anyone help me out?
(I'm using Windows XP and I have the v1.5 patch installed.)
