Missing Sound Archives & Missing Files

Acoustic Agent Rock, Studio, Vintage and Percussion Standard kits will not load. I have reinstalled GA4 (32-bit option)and the 4.2.0.290 update but these Agents don’t work. Acoustic Agent SE Studio, Beat Agent SE, Beat Agent and Rock Pop Toolbox all work without any problems. Does anyone know how to resolve this issue?

Groove Agent 4 is now working. I reinstalled GA4 with the discs from the Steinberg store not the online download links. Cubase Pro 8 64-bit would not shutdown after closing a project on my Windows 7 64-bit PC, had to install Cubase 8 32-bit instead. I had a lot of problems with Cubase 8 and GA4 but now everything is working.
