Hi,
it depends on your current version - but when you want to be on the safe side, then uninstall your current app and reinstall it from scratch … You can download the latest version from the release notes here:
ATTENTION! I speak from the MSFS Navdata installer (now the official name “Navigraph Navdata Center”) - not from the charts, nor SimLink, nor FMS Data Manager … only just for clarification
