I recently found out that big parts of my Chicago o'Hare and Zurich scenery's are missing. Also is AES for both airports not working anymore. I'm using AES version 1.9.7
When I look at "about" in Flight Simulator it says that the scenery is active.
I had this same problem with Chicago o'Hare earlier this year, after an installation of Chicago Midway from Flight Tampa. I have the idea that if I install a new/another scenery, something with the products is going wrong. I would like a quick solution for my problem, because I'm not able to use both airports now.
