After a long while of wondering what was wrong with the audio on my laptop intgrated webcam, I got the microphone fixed.  Now, the application window says that Advanced Video FX Engine has stopped working.  I check in my Programs and Features window, and the application is there, but with a blank page.  How do I update/re-install this to my computer?  Because of it, I can't use the fun voice effects on my webcam.  Is there a safe site to re-download it to my computer, or on one of the many disks Dell gave me when I received my laptop?

I own a Dell Inspiron 1525 laptop with Windows Vista Home Premium 32-bit version running with Service Pack 1.
