Hi Terry,
Please have a look at the manual "Known Issues" additionally.
1) ... a re-install of Tongass Fjords FSX is recommended...
Btw, putting the libraries (talking about EZ, RWY12, CeyX, RTMM libraries) at the top of the FSX library causes many problems on my system. I have unwanted trees, bushes, shrubs in many parts of the Orbx sceneries (like on runways, in water a.s.o.)
But that seems different from computer to computer.
