it I just updated Character Animater and now none of the tools are working. For example, if I click the stick or the dragger tool and move with to the picture, the cursor turns into a circle with a diagonal line through it.
For the tools that operate on a mesh, you have to select a layer or group with a mesh first. Currently you have the root of the puppet selected, and since all your top-level groups are independent (crowned) — as they usually should be — the root group has no mesh of its own. So to enable those tools, first select the layer or group that you want to operate on.
(And sorry the cursor feedback isn't more helpful in guiding you to this solution!)
