Could not find valid AFCAD data at this position
d00nicus:
GSX is throwing this error at every airport in the sim, across P3D 3,4 and 5. It seems to work fine for the first couple of runs, and then will stop working with no other changes being made to the sim and no other addons being added or removed.
I have already completely disabled Antivirus protection for the entire machine, run live update (and reinstalled GSX/Addon manager completely) multiple times. Reinstalled all three versions of the sim and experienced the issue identically every time.
I have also purged the cached data in ProgramData and rebuilt the cache more times than I can count.
This occurs even on copies of the sim with no third party scenery installed. AI traffic (if enabled) will follow the AFCAD correctly, and other addons (if installed) such as UGCX will also read the correct AFCAD for the airports and pathfind correctly for pushback + towing to other parking positions.
Once the issue starts occurring the "Customize parking position" option disappears in the GSX menu, and the log shows that it isn't even trying to load an AFCAD (not even the wrong one!)
In the attached log, it should have been loading the AFCAD for EGSS

Nobody ever reported this problem before. Your log shows something that would be basically impossible, as if you had NO files in the simulator folder. Since this clearly cannot be, the only possible reason I can think of, is ANOTHER program locking the same files for reading, which is wrong, since there's no reason to open a file that should only be *read* in Exclusive mode.
This program might be:
- the antivirus, locking access to the simulator folder. Configure the antivirus to exclude the whole Addon Manager folder from scanning.
- another product that needs to read the scenery library and has mistakenly open the files in exclusive mode. Disable all other add-on and try to rebuild the GSX cache again.

As posted, this is also happening on clean copies of the sim, with nothing else installed, and anti-virus is disabled for the entire system.
Is there any way to increase the verbosity of the logs to get better visibility of where it's failing?

As explained so many times on the forum, the antivirus should NOT be disabled. We have countless of evidence that, unless the antivirus is completely uninstalled, it will never be really "disabled", even if it looks like that, because the low-level antivirus service is still running, and the only way to stop it is to remove the antivirus entirely.
That's why we never suggest do disable the antivirus but, instead, add the proper folder to the antivirus EXCLUSION, so you can leave it enabled, as it should be.

No, there isn't, because the logging is normally supposed to catch real errors, like an O/S error reading a file, this is the first time ever in almost 10 years GSX is out we seen something like this.
Just to be sure: are those paths where the simulator is really installed ?

So, try again adding all the Exclusions to the antivirus.
