Groove Agent 5 kits not available

I am a newbie to Groove Agent 5 - just bought the full version, and it is “activated” in the SAM. I am trying to load kits suggested by a tutorial, but am finding that there are few available. Most display a red circle with a horizontal line. Does this mean they are installed in the wrong place, and would anyone know how to fix this? (Macbook Pro) Thank you!
