(Moderator note): This game/engine doesn't work for a lot of people, most may just come up against a black screen with maybe some white borders. And it can't be closed normally in that case. It also changes your colour settings, which to fix you should restart your computer. But it works for some, though hopefully the uploading user will see this and fix it or remove the program.
Again a new engine because the old one sucks on Vista.
