1 day I was messing around with add-on aircraft, and then I decided to run FSX. And somehow, when I click the change aircraft tab (both in-flight and when setting up a free flight) the system stops responding and obviously I reboot the sim. Its been happening since then. Then on another day, when I start FSX, it asks me if I authorise the add-ons! I have done that before, and scared of a data loss, I checked the aircraft files. All the add-on stuff for the aircraft.cfg's are missing! Then when I run a mission, after it loads a bit, the "I-knew-it-might-happen" CTD comes! Annoyingly, it reboots, and somehow I was out of the room for a moment to get a drink, and when I returned there was the FSX startup splashscreen on the desktop!I was totally confused. Anyone know what the heck of the problem it was? :(

:( YES!I can't believe it. I fixed the problem!If anybody wants to know the cause, it was squawkbox.
