make midi loops instantiate from Media Bay with Groove Agent NOT GA SE

Background: I think when I installed Nuendo, I didn’t install Groove Agent SE because I owned the full version of GA (v5).

The problem: when I access most of my midi loops in the Media Bay, they want to preview using GA SE (which doesn’t exist on my installation, so no preview).

The question: How do I reassign midi loops in the media bay to instantiate with Groove Agent?

Further context: this also means that when I drag a drum midi loop from the media bay into a new track, the instrument selected to play the midi does not exist, and gets “!!!” placed around it (see attached pic).
