Which proxy goes with the cgc-box_rig and how do you implement it?

I've linked in the scene, rivet and his corresponding proxy & the cgc-box_rig.  I am having a hard time setting up the proxy for the box.  I have chosen all of the options from the screen shot and can't seem to get any ability to manipulate the box.  Wayne, what might I be missing here?   Thanks
