Umberto,
I own FSDreamTeam airport Zürich LSZH and GSX Pro and I have the following problem with GSX gates customization:
I have edited the gate A17 and this modification was written inside the file "lszh-fsdt.ini" on location "AppData>RoamIng>virtuali>GSX>MSFS>".
But, unfortunately, on each GSX Pro update, this file is overwritten with a new file and, of course, I loose my gates customization. I don't understand why this happen, because with other airport addons, including the other FSDreamteam airport Basel LFSB, which I own too, it does NOT happen.
Is there a way to avoid this and be sure my LSZH gates customization remain safe, even after GSX Pro updates ?
