I installed the game using this site's XP/Vista installer, and it does run without those handler errors now. However, if I move the mouse up and cause the menu bar to appear, the screen immediately goes black (except for the menu bar) and won't come back. Aside from that, the game keeps running - I can still click around and stuff. I've tried restarting the game, as well as uninstalling and reinstalling, and I still get the same error. Help? I'd rather not have to go through the game being unable to save.
Operating System: Windows XP Professional sp3
Machine: VMLite XP mode (virtual machine)
Graphics Card: NVIDIA GeForce G210M
PS: I don't know if it's relevant, but the same thing happens if I try to use VMLite's fullscreen mode, even during the opening movie.
Edit: This time when I ran the game, the screen was black from the start.
