This issue just occurred. The game worked fine for over 20 hours with the Logitech G940 flight kit.
Now it tells me i have an xbox controller in addition to the G930 and it wants me to calibrate. When I click the 'go to joystick calibration settings-something' it just closes/crashes. No error messages, no sounds. Just gone. If I click 'ignore' I can start a flight and all that, but whenever I try entering the Settings menu it simply closes/crashes.
I tried restarting both the game and the computer. Have not tried a reinstall yet as I have many settings I don't want to lose.
