mogrt worked fine yesterday, not visible in Program panel today

[Emma5C30]

I put together a sequence, and I used a mogrt file from MotionArray. It worked OK. 

Today I've re-opened Premiere to continue work and although the mogrt is showing in the sequence and in the Essential Graphics panel, it doesn't appear when I play the video. 

Please for the love of god help me. This is an urgent project. I'm desperate to get this fixed. I'm running Catalina and it's Premiere 2020.

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site.

If that doesn't work, try creating a new project and import the old one into it.
