Where is your copy of X-Plane installed? We do NOT recommend installing to program files or C: if you are using the installer from X-Plane.com (not Steam). This can cause permissions issues. If your install has gotten marked read-only or is in a protected location, you may have to try to move it & repair permissions or start with a new install entirely.
