Your scenery.cfg seems ok, although you are using a 3rd party program to handle it, which added non-standard command to it, but I don't think these are the issue.
The issue, from your previous log, looks as if you are missing the main scenery AFCAD, as if you haven't installed the scenery correctly, or the files went corrupted somehow.
I asked to another user that has the Aerosoft Pisa scenery, and it worked right away with GSX with no modification needed of any kind, and GSX correctly loaded the correct AFCAD, which is called LIRP_ADEP2_ADE.BGL.
