I got the game only about an hour ago. When I placed the disc in my computer, nothing happened. I even tried getting the computer to manually start reading; not even taht worked. As a matter of fact, the computer said there was no disc. I tried on a different computer, and the game setup program started just fine. I then tried using a different disc in my computer, to see if this was all the computer or something between CoAS and the computer. The other disc worked. I then checked the system requirements for the game; my computer meets - if not exceeds - all system requirements (My operating system is Vista, which is in the required OS list). I even tried cleaning the disc (which I shouldn't have to do, considering it was brand new). And the disc STILL could not be read. I am at a complete and utter loss with this and need help ASAP.
