Groove activation in Cubase LE 10

I have Cubase 10 LE but when I downloaded Groove Agent, Cubase tell me there is an no activation license.
How can I activate Groove Agent 5 SE?
Thanks in advance

Hi and welcome,

You have download Groove Agent. This is not part of Cubase license, you need a dedicated license. Only Groove Agent SE is part of Cubase license.
