Aircraft skins don't appear in FS9

I dowloaded a few add on liveries from PMDG for my MD-11 that I fly in FS9, I was only able to get 3 cargo aircraft livers installed into flightsim, the rese just won't show up in flightsim. I ever reinstslled flightsim and still the problem presists.

I've renamed this thread for you so that someone who knows more about FS9 may see this and be able to help.

Cool thanks, bucause thogh a small problem it is annoying.

i found by turning down the security level all of the way down it solves the problem.
