VST Instrument Sets Explained, Solving Problems

No solution but as a newb, using Cubase 5, I am having the same problem with a Progressive House VST Sound Loop set purchased, downladed, installed and activated 2 days ago. In Media Bay under VST Sound , I can see the Progressive House folder and all the separate folders underneath but there are no loops or wavs in the subfolders. Hope we both get the help we need.
