Nobody ever reported this problem before, in the 5 years we released sceneries so, it's very likely your system simply too overloaded with too much things installed, and loading the airport tipped an already precarious balance of resources, up to a crashing point. The two major things that can be tried are:
- Lowering your settings, especially AI airplanes and scenery radius
- Check your video drivers and be sure they are updated, and don't use non-standard or undocumented tweaks if you are not sure what they do
- Reset your FSX.CFG settings, by removing the %APPDATA%\Microsoft\FSX\FSX.CFG file, which will reset it to default settings
- Install the latest FSUIPC, which will cure some of the graphic-related crashes ( the g3d.dll crash )
