ART Skeleton Setting Control Rig Issue

Hello, I have looked up a few issues fixes for this and nothing seems to be working. I am getting this error when I hit “Build Control Rig”

Error: ValueError: file D:/ARTv1/MayaTools/General/Scripts\ART_skeletonBuilder_UI.py line 7893: No object matches name: SkeletonSettings_Cache

Im not sure what to do. I am using maya student 2015. Thankyou for any help.

Turns out this is a problem i dont have in maya 2016

bump, I have a similar issue

still student version?
