Hey guys I know I am not supposed to talk about CD keys but this is a different situation I am not asking for a CD key however I do need help.
Summary:
So I bought Empire Total War on Steam and got Rome Total War Gold (Preorder bonus). All is good with the game however I can't play multiplayer because it says "invalid CD key". I was wondering if anyone knew where I can find the CD key I have tried looking so hard. I tried looking at the manuel (usually there is a digital manual) but there is none. I have also tried customer support for Steam and tried their forums but have failed to find a solution. Can anyone help please I would really appreciate it thanks.
