Hi Doug,
I read through this topic, because i have similar issue after updating P3D. I had landtextures at MPTO, but i solved the issue by sync the Simulator a second time.
Now i had a look to my sceneryfolder and most folder are not activeted.
I use the SIMstarter tool for organizing my Addons. You wrote to BHORV67, that mosor all scenery entrie have to be activated, avoing issues.
Can you please have a look at my screens?
Thanks
Joachim
