Hi I purchased the CS Boeing 777-300er and 777F via Captain Sim Store. Installation in MSFS went well but once I try to start the plane the displays stay dark. No FMS no PFD. Can't see anything or even setup a flight. Haven't found any post in forum regarding this problem. Do I need the Salty 747 installed? I tried both ways with and without Salty 747 installed. Problem stays the same. No displays. Please help asap. Thanks
