Umberto:
Attached you'll find screen shots along with the text file of the error report (it's long). apparently while I was attempting to follow the directions on the manual that was issued and looking at the You Tube tutorial from this forum about replacing jetways on a 3rd party airport, it didn't work for me, so I removed the excluded folder as mentioned in the manual and now I cannot get GSX to work on my 3rd party add-on. Please help me out here.
