Possible cause i see is that i'm reffering to the wrong afcad in the INI. but where to find the deluxe eham afcad?
For the same reason you can't find it, GSX can't read it, because handcrafted airports belonging to the Deluxe/Premium are encrypted in a special file, so you can't find them and GSX can't used them.
Since GSX can't use them, it will take jetway data from the default airport and, depending on the airport, sometimes it might work, but if the Premium airport have gates with different positions/names/placement, GSX won't be able to find jetways as they are in the encrypted scenery, so passengers will walk in the wrong path.
This can only be really solved after SU10 will came out, which will include a new API to read airport data from Simconnect instead from the airport files, assuming it will include data about Jetways ( the current Beta we are working with now doesn't ), which we requested to be included since SU10 Beta started.
