APX_LSZH.BGL
The older ones are all .BAK.
Will change the AFCAD to my original one to see which effect it has.
They are all correct, don't touch them.
For Flightbeam I am using this one: KSFO_AFCAD_DS.BGL
This will have the effect of losing our customization, but it would still work as it was any default airport.
BTW I checked your post on the new update, and I updated GSX while at the gate in AMS, heading to ZRH, so I suspect that this might be the reason for ZRH not working properly?
Your location when updating doesn't matter at all, you could update even when flying, if it's a minor update that doesn't require restarting.
Instead, be sure you installed the vehicles updates, because some missing model paths were fixed and, a missing model path creating a Simconnect error might block GSX.
