Hi
I feel like this would really enhance my experience when flying this aircraft.
HOwever whenever I try to replace the files in my C:\Program Files\Lockheed Martin\Prepar3D v4\SimObjects\Airplanes\CS_B757-200PF-III_RB535E4B folder, the plane dissapears from P3D's aircraft menu.
When I try to reinstall to get it back, the ACE programme tells me that the aircraft files have been corrupted  :-/

Am I doing this wrong or can anyone help me out?
Cheers
