FS Navigator issue....

Couple of things with FS Navigator.On larger airports I often get "too many waypoints found" and I don't always see all the gates or runways at a given airport. Specifically, the Fly Tampa Miami International scenery. None of the runways show up in the display window of available gate spaces, etc. When I save a flight and it asks me where I want to place my plane, I only see a few gate spaces at Miami. Have I maxed out FS Navigator's database?Also, I can't seem to add any new aircraft to the aircraft configuration area. I can see them in the aircraft.ini file but cannot see them in the actual display window that shows the aircraft.I was able to add some before. Then I deleted some and now can't add anything new that is visible.Great program otherwise but I'm puzzled by these issues.Thanks for any ideas.
