Reinstalled on another PC and to my delight the sim found all my previous 'stick settings and even has a record of the places I'd flown in the Yosemite bush flights.  I understand these things are saved online (along with my inside leg measurement, I bet...) - But I've lost all my progress - over halfway.  Any ideas if there is a file or folder I can copy over from the old installation to recover that?  Thanks.

Sounds like a bug, should be reported as a bug in zendesk.

ok, thanks!
