I have the same problem. I installed RNS maps v.12 but I am failing to activate the maps. I am not able to access the activator that you are referring to. If I try to access the link you referred to it's not in English so I can't understand what's being said. Could you please kindly assist. Thank you.Solved!
With the activator found here: touareg-club.net/forum/showthread.php?t=108444
Pop-up message is in Cyrillic, but seems to say press button to re-boot.
