Hello again,

could it be an scenery problem? its only on LGSA from HSP(Hellas Scenery Team)...

That error is surely an error in the scenery AFCAD, like overlapping nodes, orphaned nodes, missing links, unconnected parking, etc. You can check the scenery AFCAD for errors using the ADE or AFX "Faults Finder" option.

Thank You for answer.
i have deleted this scenery, no accurate AFCAD found.

That's normal, the scenery and GSX won't work without the AFCAD, you shouldn't delete it, you must FIX his problems or, at least, report them to the developers.
