Your 2nd message is even less clear than the 1st one, let's try it again:
- It's just NOT possible you don't see the settings suggested in the Design Notes, because those are standard in FSX, they are under "Options">>"Settings">>"Video">>"Scenery"
- Your problems doesn't have ANYTHING to do with activation or registration, if the scenery is not registered, it will run correctly, just for 5 minutes at a time.
- Is still not clear what do you mean with "my runway looks is like a desert". Do you mean that everythign is correct EXCEPT the runway, or the whole scenery is empty ?
