ADCAD-missing planes on ramp

I opened Andrews AFB in AFCAD and added F-16's, F-18's and KC-135 on the East side of the base where they belong. I then added Gulfstreams and C-32's on the West side where they belong. I did a "save as" to FS9 as per the instructions in AFCAD. When I reloaded FS9 the a/c are missing from the ramps. When I open FS9/scenery/addon there are no .bgl files shown, but if I hold the cursor over the sub-folder "scenery" I can see the .bgl files. If I double click on the sub-folder however, it is empty. I tried copy/paste and dragging but they will not show at ADW when I fly around the base or taxi around the base. So, where are the jets???? I even re-booted. Help!
