Hi, dwalker,
After much research on the web for this problem, it could be you need to update your video card, with any updates that you can find on the manufacturer's website.
You can also go to Start/Search (or Find), then type in PRISM3D.LOG
When you find it, left double click on it to open it, then it should tell you what the error is.
Also, here is a link for more information. I could not find "unlimited hunting 3", but did find "Hunting Unlimiting 3" game.

If it's the same thing, this site gives the "requirements" for running it.
I hope this helps, and if it doesn't, please post back, with the name of your video card, and maybe someone can you find the latest update for it.
