Hi Dave
Sorry to hear you're still having problems.
Funilly enough,I've just experienced (again) a similar problem, having purchased a new laptop.
At the moment, I haven't established , or had chance to access the internet with the new laptop to download the new database file, so thought I'd be able to simply dump the file from my old laptop onto the fresh install on the new laptop.
The file appears to be there, appears to be the correct size, but on opening up the software,it appears not to work correctly - there are massive gaps appearing in the info I'm picking up, and the navdata file only has around 80k records in the aircraft table.In other words, it appears to be viewing the old navdata file.
I've tried both overwriting the old file , and also deleting the old file and then dropping the new one in, but to no avail!
I'm presuming there some fancy workings going on in the direct download functionality from AirNav that allows the new file to be correctly installed???
Has anyone else tried this route?
