MAPC2MAPC

Hi I've been trying to get some GeoTIFF maps of New Zealand that I have converted to bcnav format to display in app but am having no joy.

Directory structure looks the same, files are name ####.png.bcnav

Am I missing a trick? If anyone would like a crack at it here are some links.

GeoTIFF files I am using can be found here: http://www.linz.govt.nz/topography/topo-maps/map-chooser

MAPC2MAPC can be found here http://www.the-thorns.org.uk/mapping/

MAPC2MAPC bcnav help file http://www.the-thorns.org.uk/mapping/help/bcnav.html

Any help would be appreicated!
