It says it can't find any game data in the D drive (my DVD-Rom drive). Checking the site's FAQ, it says that it only works with the original CDs/floppies. The one I have is a re-release with 2 games on the same disc. Grrrrrage.

You have to put the game files in the root C drive and not in the conveniently-named folder of your choice, though, which is rather asshat.
