SektorasXIII

Hello, I have been following this guide http://www.ladymoiraine.com/forum/index.php?topic=6131.0 to create a new mesh. I do everything correctly, except the 'properties' on nitrishape step. The 'properties' is bold and I cannot choose it. I do everything else as said and the mesh I am trying to import to the game seems as a big white exclamation mark. I edited some earrings from H66 earrings pack for personal use. Any help would be appreciated. If anyone feels like helping let me know.
