I have a scratched call of duty four disc, I can sometimes get to multiplayer games, and cannot play single player or some multiplayer maps.
If I download call of duty four onto my hard drive from my friend's disc, can I then play it fully by using my disc to start it up as well as the downloaded call of duty four to play the game?
