I know this is an old thread, but I am having the exact same problem, so thought I would tack onto this one.  

I'm using CC for Mac 2018.  My Premiere version is 12.1.2.

I don't have a lot of experience with MOGRTs, but after watching your excellent tutorial videos, I'm giving it a try.  When I go to the Essential Graphics Panel, I see plenty of built in free templates, but only about 10% of them seem to work.  Those 10% act as the tutorials say they should -- when I hover my mouse over them, I can see the demo animation and I'm able to drag it onto the timeline with no problem.  For the other 90%, however, the thumbnails in the browse tab don't react when I hover the mouse, and when I try to drag them onto the timeline, I get the grayed out "nope" icon with a circle with a line through it. 

I recorded a video several months ago when I first tried this, demonstrating how some templates work and some don't.  Unfortunately, now I've found that most of the few templates that were working when I recorded that video are now no longer working.  

I also tried buying the Adobe template "Simple Text Box."  (AdobeStock_299388787)  It showed up in my browser window, but then when I tried to install it, I got the error message "This Motion Graphics template is not compatible with this version of Premiere Pro."  I wish the Adobe site had informed me before I plunked my money down that I needed a certain version to use the template.

At any rate, I still can't figure out why the majority of free templates that came included with Mac Premiere 2018 do not work.  Not sure if it's a version issue, though I'm in the middle of a project right now with deadlines, so terrified to upgrade to a newer version.

Computer I'm using is a mid-2014 MacBook Pro.  Other than the MOGRTs, the rest of Premiere seems to be operating fine.

Thanks!
