I will write to you Step by Step of what to do and you follow the steps and i'm sure the game will work....
1.First Make a full image of the original game* using Alcohol 120%
2.Mount the image with deamon tools 4 and run the install from the image and not from the Dvd.
3.unplugg all the Dvd drives(Cd drives may be needed too!)
4.and now just enter a serial number and enjoy.
