If the thief has minimal knowledge as we teach in Noeman, he will be able to unlock the map and delete your .unl file in a half of minute…
And if the MapID >= 2200 you will get the "Unauthenticated" status: [Only registered and activated users can see links. ]
I don’t see for what you make this; and as catymag says, better you use the last version of the map.
Hope been helpful.
