When I open my Add/Remove, all of my programs do not appear on the list. There is actually a HUGE gap between the 'L' programs and the 'W' programs. Does anyone know how to fix this?

 

(I also believe my Windows Movie Maker program is crupted. Is there anywhere were I can repair this or redownload the software?)

 

Thanks for any help! This as been a problem for me for way too long now.
