NB
I believe so.....The file is in the Data folder......and yet I see no new file
You may have more than one occurance of Airnav on your computer and if so the system may be reading the wrong one, or you installed to an incorrect location. The Navdata db.3 file you should have in your data folder will be Navdata.db3 dated 29/1 and there will be another 3 Navdata, files. Navdat db2 bak, Navdatadb3 journal and Navdata-backup db3. If this insnt the case you may well have installed somewhere else in the wrong location
Is your Radarbox installed to the default c+\programme fiiles\airnav\radarbox location or did you install to somewhere like c:airnav\radarbox\
Install the update to where ever you installed radarbox and only go as far as airnav\radarbox and dont go as far as airnav\radarbox\data.
Once installed go to database explorers and open the aircraft table and that will advise how many aircraft it is reading.
