Yesterday I downloaded X-Plane 11 beta to my computer, I started a flight with the cessna 172 and everything worked correctly except the fuel selector lever, it was backwards and didn’t turn. In the 737-800 practically nothing of the cockpit worked, I couldn’t turn on the batteries, fuel pumps, parking brake, etc.
I tried to reinstall the simulator but these problems continue in all the aircrafts.
What could I do to fix these errors?
