Groove Agent 4 lost a kit

I originally posted this in the cubase forum, so I’m reposting here

hi, for some reason my Groove Agent 4 has lost one of its acoustic kits, currently it has a Red rock kit
Maple studio kit
White vintage kit
there used to be a 4th one, i cant remember what its name, another rock acoustic kit i believe, but it is no longer listed in the kits, I tried reinstalling groove agent 4 full install and content but still a no go, anyone know the solution? thanks
