Since you mention it yourself... TU also crashes on my Vista installation. It loads and shows me the main menu, but when I choose to start a new game, it goes bye-bye with a Blitz3D error message. I haven't run Windows at home in a couple of days, and I don't remember what it was. If it's important, I can run it again on the weekend and post the exact error message here; but don't expect a result before Saturday or Sunday.
