I have downloaded the unlocked files city navigator 2013.30 Installing in windows vista was no problem. I have unlocked the map with keygen. Afterwards i have tried to install the map in windows 8. I also have run keygen. When I opend cn 2013.30 the program (mapsource) gives a message that cn 2013.30 was not verfied, so i cannot see the details op the map. I want to look for an solution.
