I had my AV totally shut down(bad move) after extracting the zip file I put it in admin and it loaded great. only half of the OH Panel switches worked and none  in the cockpit. I'm running a Gravity GTX (Jetline Systems) . I get great fps with ORBX, Chaseplane, and weather all in VR. I've had this machine for just about 2 years and every time I put the CS 757 in P3Dv4.5 I have to fight it just to get it to fly. I loaded XPlane 11 and went with FF 757. IT Works
