I had to reinstall P3D and I used this opportunity to go to P3D V5.3.
My P3D sceneries are still on my computer in a separate Orbx library.
But how do I install these sceneries again in P3D??
I could not find such option in Orbx Central and when I use the option "Add scenery" in P3D, I get an error message (scenery inconsistency)
