I also found that I also could not run the game and it would completely reboot my system, after toying around with drivers etc for a while I found that if I reset the display options (through the original popup menu)to their original lowest settings the game would start & run ok.

One thing I've noticed is that the dynamic shadows option in the popup menu actually seems to be configured back to front ie - if you select "on" in the dropdown shadows are turned off in the game (you can check this in the options screen) and vice versa.
