I have added the Nepal Deluxe Parts I and II scenery packages. Now I am sure these are good add-ons and most likely it was something about how I added them, but now I have runways floating in air, some stuck in the hillside, when I select the outside view, I get the top down view only and a bunch of other bad stuff. To cure this problem, I tried adding the latest version of the Lukla Airport package including the scenery fix, which helped a little, but still most of the runway is stuck in the mountain. I decided to delete the entire Parts I and II folders from the add-on scenery main folder which did not help much. I also went to the add-on scenery scenery file and deleted the Nepal BGL's and any other associated files with Nepal or Buthan airport ID's. This did not seem to help much either. Funny, because I added the latest version of the Tribuvan airport scenery and it worked great. Now, I know to back up files, but I think the deluxe Nepal scenery only included the folder additions to the add-on scenery main folder and no other changes other than activation in the settings tab.
The question is simple, where do I go from here to at least restore the scenery to the original FSX configuration and how could I have gone wrong in the original installation? Thanks for any suggestions the scenery community may have.
