I don't see a map listed for the device, are you sure the map files are inside a folder in the root and not in another sub folder?
What map are you using?
Have you done a hard reset followed by the TT clear flash tool? If not do so.
If still no joy I suggest a clean install of NC and map on an empty SD.
