ART tool Can not progress due to grayed out button
While this post is a bit old I came across the same problem and found a solution.
At the top select A.R.T.1.0 and then select Character Rig Creator. It should recognize the Character Rig you have already started and the Skeleton Creation and Deformation Setup buttons should work again.
Hope this helps.
