I purchased the two cd edition from a local Circuit City, which has one of those wonderful return policies that doesnt allow anything opened to be returned. The installation worked just fine but then when i try and run the game i get the Bad Disk error, (please insert disk one) i've tried everything and it still doesnt work. I was wondering if people have had better luck with the D2D version, ill accept that it doesnt work but i want to buy a version that does. Thanks for any help you fine folks can provide me.
