I have a similar problem - installed Songwriter Essentials, but have only the Groove Agent bank available (no Groove Agent SE options. Cubase 9 has only the SE version active, so I cant get it to work. (Blues Essentials installed OK with both banks available, by the way. So it seems that Songwriter Essentials is at fault). Tried re-installing with ‘for all users’ option, but no change. Steinberg Support has not replied for 20 days… [I don’t really understand how to do Bandini reply above]. Thanks if any advice. Regards
