OMG DaredThread was here!!!
Well i got halo combat evolved a while back, along with halo custom edition. Just in case i ever lost the disc for combat evolved, i backed it up on a blank disc. I lost combat evolved about a year ago, but i didnt care cuz i was too busy playing halo 3. Well today i decided to play custom edition, so i try to use the backup disc for combat evolved to use custom edition, but it won't let me on, saying that it was the wrong cd rom.
How can i be able to play custom edition now?
