I had the same thing happen to me, but i read the ReadMe file and it said to backup my things so i did.
it was only a matter of going in and retrieving the aircraft.cfg file and presto - all the skins are back.
I have since reinstalled the upgraded cockpit but i dorked it up and backed up the new aircraft.cfg file instead of the old one which is now gone.
i could really use the old 737-800 aircraft.cfg file now

LOL
such things are minor inconveniences really.
dont let this sort of thing bug you - either one of you.
