I wonder if you have some experience in doing export to new Wayfinder software shipped with Diablo? I tried to export data using Extension Editor, but created .nce files have bad format - i get message like "Extension 'something.nce' not suited for this map"... But location of extension files seems to be ok, since it tries at least to load it. I tried also to use Extension Editor in raw mode, which generate separate files .qt .poi and .mbm, which can be then copied directly to /map/mapdata/poi/extension_name_dir. When using this solution i get no error at startup, and new poi category is succesfully added. But when i try to view poi points i get empty list. After some testing (using files from existing "WLAN-hotspots" category) i came to conclusion that .poi and .mbm files are correct. Do you have maybe some idea how to get .qt file in new, proper format?
