URGENT Vista Visual Master Error Boot Screen Change?

I downloaded 'Vista Visual Master' and changed my boot screen. That was successful. Now I want to change to a different picture; so I create a new MUI file using Vista Visual Master. I try to apply this new file but I get this following message:



Unhandeled exception has occurred in your application. If you click continue, the application will ignore this error and attempt to continue. If you click quit, the application will close immediately.

Attempted to perform an unauthorized operation.



I tried to change it back to the default (I have a back and Vista Visual Master has the option to do that), but I get the same message along with a 'Pathway Denied'.



How do I solve this problem? I'm using Home Basic with SP1URGENT Vista Visual Master Error Boot Screen Change?
Have you tried uninstalling Visual Master? If not, try that.

There are only two other options, first, try system restore, to the point before you installed Vista Visual Master, otherwise, press F8 at your next boot and select Launch Start up Repair (or similar option), if your laptop supports it, there should be an option to reinstall Windows Vista, if not, your laptop may have come with recovery discs.

Hope this helps, maybe modding with free software isn't always a good option. (:
