Solved my problem of my custom scenery not showing up. I decided to upgrade to KJFK v2 and see if it would install, well it did, so then I moved the New York City scenery back into the Custom folder, and it worked. So I decide to remove all of the other scenery's out of the custom folder into a temp. folder, started up X-plane 10.42, then shutdown, then moved the scenery's back into the Custom Scenery folder, started up X-Plane again, everything is back to normal. Something to remember.
