KLAS displays properly but the terminal builds at KORD and KJFK will not display. At KORD I get the light standards and some roof structures but the rest of the terminals won't display. I am perplexed.
If you see KLAS, it means the software is running properly, and it's the same that is handling all sceneries, if you see one, you should see the others. If the software is not running, you wouldn't see any scenery, not just one.
If you don't, and you DO see everything correctly at KLAS, which means you see both the Addon Manager and the Couatl menus under "Addons" (which you surely do, otherwise you wouldn't see KLAS either), it means something that doesn't depend from the scenery, but something else that is excluding it like, as usual, another AFCAD coming from another product that is made for the default scenery.
