Animation Rig Question

I have just bought a tutorial that does not talk about how to setup it’s rig. The rig is also BlendSwap and is called the Flex Rig.

I am using the latest Blender version and when I open the rig file nothing is there. Is it hidden and just not visible? Any help would be greatly appreciated.

Thank you,


I just figured it out. I clicked a button that reloaded it or fixed an error. Have no idea, but it works.
