Problem running visual styles

[sedd_18]

I was trying to install visual styles using the hacked UxTheme.dll file with no luck, the visual styles weren't showing up on my display properties options. So I reverted the file and thought I would give XPize a shot. It installed fine and all the visual styles show up but when I try to change them I get this error message:

The Visual Styles could not be loaded because the file failed to load

I click ok on that box and then if I click ok on the display properties box it gives me this error:

Run a DLL as an App has encountered a problem and needs to close. We are sorry for the inconvenience.

I tried restoring my system back to a know good setup using the system tools but no luck. Any ideas on what could be causing this problem? Thanks for your time.
