When I installed opensceneryx for X-Plane 9 onto my windows computer, I went back to x plane to see the new features. when I went back to the airports, (which previously had scenery), there was nothing! I did everything right, I installed opensceneryx into my custom scenery folder, then it said it was successfully installed (after 3 hours of installing). What did I do wrong? Is there a way to fix this?
