Since Rotterdam professional was cancelled, I installed the 'old' Rotterdam X version in P3Dv4. Everything OK except for the runway lighting and PAPI. I converted the AFCAD file to P3Dv4 and manually added the runway lights. Now the airport is completely usable!    To install: - Go to the Rotterdam scenery folder (Aerosoft\Dutch Airports - Rotterdam\Scenery) - Rename the file AF2_EHRD.bgl to AF2_EHRD.off - Unzip the attachment and place the file in the same folder
