When I Go into the fms, there is no navigation data at all, when I enter an airport in the apropriate field, I get an error message telling me it's not in the database...I've reinstalled the pmdg package and installed SU1 but no luck. Has anyone seen this before? or know of a way to fix this?Cheers, Joel

Yes, Download the navdata as indicated in the FAQ's and support pages at www.navdata.at. That should do the trick!
