OK, after my last post and despite trying everything I knew (and thats limited), I ditched the Airnav and tried one of my dongles........and it worked, after downloading the updated drivers from Zadig. The only problem I seem to be having now is when I go to update the airnav Db, it behaves itself until about halfway through the download then just stops. I have tried several times with the same result. At first I thought it may have been a memory issue so I transferred all airnav files/program from the C drive to the D drive which is a new 1tb HDD but the same result ensues regarding the datbase download, any suggestions??
kind regard clive.
