Alan Morgan Signature Drums


I’ve recently upgraded from Cubase 6.5 to 7.5 by download - I use a macbook pro. I was trying to follow a YouTube video on grove agent 1 where it was about loading alan morgan signature drums. I can get to the bit where i load a preset and I can see the Alan Morgan Signature Drums folder but there is nothing in it. Any ideas how I can find the content?
