Alright, I have to ask someone to please make a topic about running FPSC on Vista. Basically what you must do is right-click on the FPS-Creator shortcut, go to properties, go to compatibility. Run in compatibility mode for Windows XP Service Pack 2, and then check the run as administrator box. I cannot stress how much we need a stickied topic about vista, could a moderator please make one?
Edit: Your problem sounds weird, but there are many versions of Vista so I don't know what to tell yeah, just try this, it is a common problem for compatibility with Vista, and everyone says Vista has compatibility issues, the only true one I've ever had was for a custom program somebody made that didn't run for creating servers in RPG Maker XP.
