The game requires an Intel 900 series chipset or higher. The 800's as you have simply do not have the needed hardware functions, and unfortunately no amount of driver updating can change that.
If you don't have another machine and can't upgrade, you may be able to obtain a refund depending on when/where you purchased the game. If you bought the game direct, contact sales@stardock.com, or see
here for further details if you purchased the game at retail.
