No NAV DATA bug Xbox marketplace 77w

Three days ago I bought the pmdg 77w on msfs 2024 However, a problem immediately appeared to me: it didn't accept any ICAO, it always told me NOT IN DATA BASE. I play on an Xbox Series X, and I've tried everything to fix it. Restarting, uninstalling the app, and playing over and over again, but nothing. I suspect there's a corrupt file, often in my Attempts to uninstall and reinstall the plane resulted in a failed download. So I assume there's a corrupt file, but even deleting my personal data didn't fix it. So I'm asking for help from anyone who might have any ideas on how to fix it.PS: I don't have Simbrief and use the Italian language console if it can be useful.Thx. It hasnt any NAV DATA.
