I'm having almost the same error here. The error I am getting is GSX is disabled by user settings and to update from marketplace, or something to that effect. I purchased it from the marketplace a while back. I fly form KCLT a lot and never had a problem with it. The last time I flew from it last Wednesday and it was working normal. I did the update last night (18SEP23). Now my GSX doesn't work at that airport. I uninstalled it and reinstalled it hoping it was just a hiccup but that didn't work. Hopefully it can be fixed soon.
