X-Plane 11 Cycle mismatch

very good I have the xplane 11.51 already has the last three updates that I get this error;
"LOADING NAVIGATIONAL DATA FAILED:
CYCLE MISMATCH BETWEEN EARTH_FIX.DAT AND EARTH_NAV.DAT
THESE FILES MUST COME FROM THE SAME DATA CYCLE.
PLEASE NOTE THAT X-PLANE 11 IS NOT COMPATIBLE WHIT NAVDATA FILES MADE FOX X-PLANE 10 "
I do not know what to do

Hello Francisco! Welcome to the forum.

It sounds like you may have installed the navdata files for X-Plane 10. Please verify this and, if possible, provide screenshots of the addon list and path settings (Settings > Paths) from FMS Data Manager.

Regards,
Malte
