1) Check to see if there is an update available for that game, it may well be known to them and they may have put a fix in the latest update
2) Ask on some gaming forums to see if anyone else has had this problem, they may already have a solution.
3) Contact the people who made the game, it's their software - they know the game code better than anyone else, they should be able to assist you.
4) (I DO NOT recommend or encourage you to do this) You could search for a 'No DVD crack' and hopefully that will work. If you do go down this route because the other options have not worked then I advise you do a virus scan of the file. click here
Sorry I don't have a solution because I don't play that game or many games at all for that matter.
