Motion Generator Issues

Here's the weird scenario:

2012 MacBook Air and 2013 Retina Macbook Pro

- both maxed out spec

- both have Motion 5.3.1 and FCPx 10.3.2

- both running MacOS Sierra 10.12.3

- both have FxFactory 6.0.2 installed (Yanobox Node in question)

On the 2012 MBA, motion can load the Yanobox Node generator with no problem.

On the 2013 rMBP, motion says the generator is missing, but I have verified it in the motion templates/generator folder, just like the MBA.

There is no difference between the two...I also verified that by uninstalling, and reinstalling Motion, FCPx, FxFactory and said generator plugin. Frustrated and confused right now. Why can't Motion see the files on my rMBP?
