I got a used game and tried to activate the product code on my computer. It says "duplicate product code". Is there any way for me to play this game?
Which code are you talking about? and what console are you using?
The key code to install the game on PC. The one on the back of the manual.
Can anyone tell me, have you bought a used MW3 on the computer and then been able to load it on your computer? Is it possible or can you only use a new code for every computer?
