Groove Agent kits missing after upgrade

So … upgraded to Cubase 9 and all my Groove Agent kits seem to have disappeared. Don’t think it’s anything I’ve done - anyone else had a similar problem or could suggest a fix ? This is for the full version of GA4, not GA4 SE

Uninstall Groove Agent SE 4 (or Groove Agent 4) and all of its content and then reinstall it using the full Cubase installer. This fixes it for most people.
