Vintage Beatboxes for Groove Agent One

Im on Cubase. When I launch vintage beatboxes presets in GAO, I receive the message “failed to locate samples”. It happens only for vintage beatboxes sets. They should have been installed with update 5.5, but I only have Groove Agent 01.vstsound and Groove Agent 02.vstsound installed.

I have the installer for Cubase 5.5, but only the .exe file, no extra content were provided.

How to install "Vintage beatboxes"extra sounds?
