Jeez this is getting very very strange
Ok - I once again downloaded from scratch - this time (and to be honest, I can't be sure if this wasn't the case before?) the file downloaded at the correct file size.
Great i thought
However on opening up the Radarbox application, the Navdata file automatically reverts to what appears to be a blank file, with no data in it under any tables whatsoever (at a much smaller file size)- however, and this is the real problem, the backup file created by the process of downloading the new application, is also empty???
This happened during the time over which the RadarBox programme loaded
I've tried this separately twice now
But, it gets worse...............
I now appear to have lost all response from the network, and the 3D options also
Just about given up for the night
Alan - I've got a link into Aerodata analyser,but it's not actively running - I've also got an older verion of RadarBox on the laptop - with nothing linked, and the same happens??
