I purchased this scenery a whiles back (great scenery BTW) but on my last 2 flights I encountered a weird issue.
All runways and taxiways disapeared. Instead I had polygons where the runway lights and taxi lights are supposed to be and everything was grey. The terminal and buildings where there but nothing else.
This is the FSX version using DX10 preview. I still managed to land because I also use EFB and it was showing me directly on the centerline. On approach everything was there eg the runway lights etc. but when I got closer (4 mile approx) everything disapeared.
