I am trying to update some of the poi's on my Navigator 17 (paid for installation.) When I try to open Map Explorer 17, it says I have a time expired version, and asks for a key, which I don't have. I have lost the original download of Navigator 17- the hard drive broke on that machine- so I have no other info on this installation. I have tried inputting the data using Map Explorer 10, which works ( I still have my original paid for Navigator 10 on this machine), but it wont show the new POI on the Nav 17 map- I did copy it across to the input folder of Nav 17. Any help on this problem would be appreciated.
