I have added the ADD ON MANAGER. When selecting KLAX it states: ACTIVE but not installed in the Scenery Library. I decided to download Chicago Ohare to test and this worked. I noticed it pop up in FSDREAMTEAM/COUATL. After I installed Chicago Ohare in trial mode COUATL powered products was added t the ADD-ons menu. Chicgao worked by LAX did not which is what I paid for back in May. The KLAX version does pop up a warner that it will work only with P3D version 2.0,2.1, and 2.2
