I installed this yesterday and can't do a free flight for 30 mins or more without it randomly crashing to desktop with the message "Microsoft flight simulator has stopped working"? I'm on Win 7 64bit if that helps. I have updated my AMD graphics drivers but no joy. I've verified the integrity cache through steam and it said 1 file is corrupt, cant remember which now but anyway that didn't solve the problem. I've done a bit of googling around the specific error and often it says to run FSX in XP compatibility mode but you can't do this through Steam as far as I can tell.
Short of doing a complete uninstall/reinstall can anyone help?
