Help. I was flying and doing the missions and everything was fine until I got to mission 6. The game crashed and when I restarted the game my helicopter controlls are super sensitive and the helicopter lurches to the left every 10 seconds. I have deleted and reinstalled the game but the problem persists. As it is I can't play anymore and I don't know how to fix it. I have also checked the joystick settings and they are as they were before this problem. Has anyone else experienced this? Can you help?
