If the automatic crash report window comes up, please be sure to fill it out and send it.
Otherwise, double check that X-Plane is not installed in a protected location--this can cause incomplete updates or other strange problems. The last thing you can try is resetting your preferences to default by going to the Output folder & moving or renaming the preferences folder.
