So I pre-ordered from TotalGaming and got my email with my serial # which I used to download the preload stuff. I am having problems activating, so I decided to hit the button inside the TotalGaming Options screen to lookup my serial #. I entered my email and it sent me my serial number. Now get this!
The serial # it sent was different than the serial number I used to register the game!
WTH? I will try the new serial # to see if it lets me activate.
