This warning has started to appear on my screen when XP starts up and I have no idea for to fix it.

I have searched the manual for 'warning' and 'earthNav' and there are no references in the manual.

Could someone please give me a clue as to where to start looking.

Thanks

Did you follow the NAV Data install section of the manual? Was it working before? Do you use Navigraph for updates to AIRAC cycles?

You can also run the XP installer update and will fix any broken or missing files in the base sim such as the default nav aids data.
