So in with the ART tool in Maya, I cannot build any of the skeletons/characters. I tested this out even with all the default settings, nothing changed, and tried saving the the Sample section it creates. This is the error I’m getting http://puu.sh/7G3wY.jpg

Hi krailyx. This is a known issue. There is a ticket in our system to investigate and fix this. Sorry for the inconvenience.
