Error Opening Program

I've uninstalled StepMania 5 Beta 3 entirely and reinstalled it, but I'm getting an error whenever I try to start it up. I only have the default theme settings, so I'm not sure why it's saying this.

ThemeManager: The redirect '/Themes/DDR 5th Mix/BGAnimations/ScreenAttract out.redir' points to the file '_fade out', which does not exist. Verify that this redirect is correct.

Can you tell us what operating system you're using? I get the feeling there might be some files in your user data folder that are still being read (though you don't intend for them to be).
