I have just recently downloaded MDPP scenery from X-Plane.org, and it says it requires a bunch of different scenery librarys. So I got them and put them all (correctly) into my custom scenery folder. Then I put the MDPP scenery into the custom scenery folder as well. When I go back into X-Plane, and go to MDPP, there is nothing, No airport scenery at all. What have I done wrong? Any help would be appreciated!
