Unfortunately, some other people have reported a similar problem and I don't know what causes it =(
If you could send me the file trace.txt that is in your installation folder, it would give me some clues but so far I've not really been able to fix this. Just email trace.txt to firstname.lastname@example.org
You might also try running the game in windowed mode (use the setup tool) and make sure compatability mode is enabled (also in the setup tool). But this was tried for someone else with the same problem you are having and it didn't work!
Thanks for the report, sorry the game isn't working for you,
