Do you have the new X-Plane 11.30 Beta 6? I have noticed that the CIFP navdata found for free from the FAA doesn't work on the newest beta, but did work on X-Plane 11.26 release. I believe that this is a bug that the X-Plane developers need to fix, because I've been updating my navdata for months and it stopped working when I updated to 11.30. For now, I fly on X-Plane 11.26r2 with no problems. For now, I would just say revert back to X-Plane 11.26r2. You can uncheck "Check for Beta Updates" in the X-Plane 11 updater and update X-Plane 11. This should be a temporary fix until Laminar Research fixes the problem.
