Solve a mystery

i ask help for a mystery in my cubase 11 element installation, groove agent does not find its samples, i also reinstalled again to see if there was a corrupt file and i also extended the search to all the hd c: \ but it seems there are not. if I play in the patterns, the rhythm starts but the sample does not appear and it seems there are only the names of the styles and the rhythms.
but i also have steven slate drum ssd4 and ssd5 and they work great despite being third party.

Download and install Groove Agent library from the Steinberg Download Assistant, please.

oops! thanks in fact it worked, i thought it was in cubase main download.
I learned something else, thanks
