Deserted airport!

I recently downloaded Kai Tak from AVSim. The package is great with full scenery across the bay and on the airport including curved approach lights. I have made successful landings day and night. BUT, there is no AI the place is deserted!!!!!! They are all going to the new airport. Do I really have to delete that and if so will the AI go to Kai tak?
Short of lowering the landing fees I don't know how to entice the AI back.
Any ideas chaps? Or Chapesses!
Many thanks Vololiberista
