Blacked Out Window View

I just started installing aircraft to my CFS program. They seem to work fine and look good with the external view, but with the conkpit view the window is blacked out.
Is there another file or utility needed or are these aircraft just not useable with CFS ?
I have tried several airplanes and the only one that works correctly is "P51-RIDGE RUNNER 3".
thanks for any help
