I've had COD 2 for a while, I ran it on my old computer fine. I got a new computer during the summer and decided to install it this weekend. Everything went fine with the install, however when I put the disc 1 in to start playing the menu opened up and I clicked play singleplayer and it started to act like it was loading but then came up with an error saying enter the correct COD 2 disc, I've tried using different discs (1-6) to load it but none of them working, can anyone help me?
Have you updated to the latest version, 1.3? Also, you could solve your problems a lot easier by just getting a no-CD patch from gamecopyworld.com Lastly, "MP works, SP doesn't" is a misleading name for a topic about CoD2 not reading your disc.
