Just hours ago i bought the Rome:Total War anthology, it comes with Rome:Total war (The main game) and two expansion packs. I put the main game into the CD-Rom drive and i could hear the disc spinning around inside but it sounded different than usual. I waited for the game to start but nothing happened so i went to My Computer and clicked on the D drive to start the game but i got a message saying "Please insert a disk into drive D:". I ejected the disk and re-inserted it but the same thing happened again. I put one of the expansion packs in and it worked, but i can't play it without installing the main game. I tried the other expansion pack and that worked too. I thought it must of been a problem with the main game disc, so i tried it in a friends computer and it worked. So it's not the disc that's the problem. Anyone know how i can solve this problem?
