Maya 2015 Animation and Rigging Toolkit crashing when building control rig with no error?

hahaha for me it gives me even more errors

“ART_jointMover.py line 539: No object matches name: [‘proxy_geo_spine_01’] #
updateRendererUI;”

and then i get

Error: AttributeError: file General/Scripts\ART_skeletonBuilder_UI.py line 6229: SkeletonBuilder_UI instance has no attribute ‘globalMovers’ #

and every button is grey and freezes. im gonna try import settings and presets to another ART folder.

Edit1;
it didnt work with a fresh start either.

Edit2:
I got it working by pressing Auto world space button first then save rig pose.
with the latest Version of A.R.T
But with some errors:
“Traceback (most recent call last):
…WindowsError: [Error 3] The system cannot find the path specified: ‘C:/Users/Fredrik/Documents/maya/Latest_tool/MayaTools\General\ART\system\.
Aborting Operation. Please correct naming conflict and try again.”

Edit3: it just works some times now… its just pure luck…
