Well, apparently you DID build the game.
1. Did you put all of the games files on the CD? (game exe, files folder, ini files)
2. Are you trying to play the game from the CD or did you copy the contents of the CD to the hard drive?
3. What
exactly is the error message?
4. Does the system you are trying to play the game on meet the minimum system requirements for FPSC?
5. Does the system you are trying to play the game on have the latest DirectX installed?
6. Etc...?
MORE INFO!!!
I'm sorry, my answers are limited. You must ask the right question.
