Hi Markoz.

Yes, I changed the model via ACE with FSX off. And installed the airplane with FSX off too. But no way. I have both Nath's Amerijet (N905AJ and N994AJ), and I have problem with both.

I can't change the model manually, because if I put "model=another company", both airplanes don't appear at FSX menu.

This is the "added" text of one of them, if I want to install manually:

[fltsim.XX]
title=CS 727-200F Captain PaintXX
sim=cs727200
model=f
panel=
sound=
texture=Amerijet N994AJ
kb_checklists=
kb_reference=
atc_id=N905AJ
atc_airline=Amerijet International
atc_flight_number=N994AJ
ui_manufacturer=Boeing
ui_type=727-200 another company Freighter
ui_variation=Amerijet N994AJ, 2009 NP
ui_typerole=Commercial Airliner
ui_createdby=Nath2889

Maybe the trick is here, I don't know.

And of course, thank you very much for your help.
