ARTv1 not working properly in Maya 2018 (Student Ediction)

Although I’ve successfully installed ARTv1 for UE4.20, and with Maya 2018 (Student Edition), I’m having some troubles using it. When I use the Character Rig Creator, and I click on Skeleton Placement, it creates MOST of the skeleton but is missing virtually all of the right side components (except that it actually creates the right LOWER leg). It doesn’t create the right arm or hand, nor does it create the left upper leg or left foot. Any thoughts on how why this is happening?

ARTv1 is no longer maintained or supported by Epic. All issues and requests should be directed to Jeremy Ernst, who is the owner and maintainer of ART.
