Animation and Rigging Tools: FAQ, Known Issues and Feature Roadmap

First, very sorry for the late reply. It’s been very busy at Epic lately working on our game projects and I sadly got too caught up to remember to come check the forums. Apologies.

As for the issue, I ran into this long ago, and I think it was because I had a userSetup in my documents/maya/scripts folder as well as one in my documents/maya2015/scripts folder. If you have any user setup files in the version specific script folders, try removing those to see if that’s the issue. I hope it is, because otherwise, I have no clue!
