PreShow Bumper Set: Digital Cinema PreShow Experience Bumper Set

Hi. I can't seem to get the latest version to work. I have installed the Matt Huisman Youtube for Trailers addon but I get the following error in the Kodi log: Seems a 'Quality' attribute is missing?? Any help much appreciated. Thanks

Do you use images or videos for your ratings?

Excluding the actual hardware for your media (screen, speakers, amps, receivers, etc.) what is your favorite thing that enhances your movie watching experience?

Excluding PreShow, what is your favorite kodi addon?

I’ve completely uninstalled PreShow Experience and reinstalled. I’ve made sure the Youtube plugin is installed. I’ve enabled all sources and ran content updates several times. I start with a new blank sequence, put in a trailers module - set it to 3 trailers. Do a “preview” - it turns the screen black and then returns. I’ve uninstalled and reinstalled the Youtube plugin as well. I’m out of ideas unless someone can tell me that this is just broken for now?
