Everytime i am at Meigs in FS2002, a popup that says "Scenery object not found" constantly! How can i get rid of that? Only happens in meigs

I had the same problem until I realized I inadvertently deleted one of the default AI aircraft. I compared my FS2K2 CD with my aircraft directory and found the missing aircraft. Extracted it from the CD and have had no scenery error since. Hope this helps!
