I updated nave data with navagraph and now x-plane wont load. I get the folowing error message.

"Cycle mismatch between earth_fix.dat and earth_nav.dat These files must come from the same data cycle.

Please not that x-plane 11 is not compatable with navdata files made for x-plane 10 "

Can you confirm you did follow the instructions given in the readme.txt file you can find in X-Plane 11\Custom Data?
