I am having problems with LEIB - Enhanced. I have no terminal buildings and all the trees and GSE vehicles are pink. I upgraded to the enhanced version. I did uninstall the scenery and re-install fresh, deleting the scenery dat files. First visit to the airport, everything was fine. Now, subsequent spawning/arrivals into LEIB it is back to the same. I have attached a couple of screenshots. Any help would be much appreciated. Simon
