I've been using GSX for a long time in FSX and Prepar3d v3, and today I installed it in v4 as well. The install went well, all works as expected, looks great, I can call all the services etc, but all the parking/gates show default vehicles still. Not sure what I've missed, it certainly looks like it is installed properly, and displays GSX vehicles in v3, just not v4.
Any clues as to what I need to do?
