Have you installed the V6 software to the program files location or did you install to the recommended c:\Airnav
I believe that your issue was unconnected to the post at the start of the thread as your issue was on starting up, unlike Shanes issue which is while in use and you would see not responding on the top line title bar
On starting up the map should go to where it was when you closed down. Are you using File/Exit to close down as if the red cross (top right) is used all changes are lost on closing. The map in use is shown on the top line after the software version for example mines shows default.ml4, what does yours show
