Its just a regular .3dm file. I've changed the "ñ" of "Diseño" for an "n" and it worked. Something weird happened with the shortcuts when I used that letter Ñ. When I added a shortcut whit the letter Ñ from the MoI options panel, then closed MoI and then reopened it changed the shortcut to a minus sign if i my memory is ok. I added that same shortcut to the .ini file and then it worked on MoI.
