Hi Ray,
I am not with Laminar Research; just a flight simmer.
What version of X-Plane 10 are you running? The last (final) release before x-plane 11 was released was version 10.51. There has been no other releases. Download this latest version and my interpretation of your problem should no longer occur.
X-plane 10 and X-Plane 11 will not mix if trying to update from 10 to 11 into the same directory. Completely different programs/software.
If your "configuration " problem is for different aircraft, X-Plane 11 now has the ability to save for each aircraft situation. X-Plane 10 cannot perform this same function
