Have had this installed previously and finished the game a few years ago - decided to give it a whirl again and after installation attempted to start from shortcut on desktop only to be met with a dialogue box containing the following :-

Can anyone help?
Running XP Home legal with SP3 - Nvidia gforce4 Ti 4200

Many Thanks in advance.

I know they're a little old, but are you using the latest drivers for the Ti 4200?

downloaded the drivers from Nvidia and installed - game working fine now - Many Thanks

Since Jan 2009 I recovered my system after a crash using a quite old image - obviously drivers needed updating.
Thanks again
