Paul,
Yes the user name and password on the CD should be inserted in the approriate position on the signing in screen with the remember password box ticked.
The version that comes in the box, 2009 is not the latest version. Also you will probably have installed to the default location in programme files, this causes poroblems with the windows virtual store.
My suggestion to you will be to uninstall the version you have installed and to down load and install the latest version from the website
http://www.airnavsystems.com/download/anrb/403/ANRB403Setup.exe It is quite large and will take 20 minutes or so to download.
To avoid virtual store problems do not install to the default programme files location but install to somewhere like C:\Airnav.
Once installed, then add the 64bit drivers as before.
Once done, attach the USB cable etc and turn on Airnav and see what happens
Alan
