Fonts and UAC

I recently bought Print Shop 22, but some of the Windows fonts cause the
program to suddenly shut down. Fonts like 'gulimche, geobats, and batang'
seem to cause a lot of problems on my system. I try to delete these items in
the fonts folder, but UAC doesn't allow me.
I am the administrator on the computer, and I selected properties on the bad
fonts to try to get rid of them and went through all the advanced windows,
and they all said I had full control, yet when I try to delete the system
still claims I don't have permission.
I have never used these fonts in Vista or in XP, and they do nothing but
cause problems and I want them gone. How can I delete them to use my
publishing program freely?
