Missing sound files in Mediabay

I’m using Cubase Artist 6.5.5 and I’m unable to locate certain sound files in Mediabay (Groove Agent One, which, from what I understand, is a completely different program than the ones that can be bought separately).

For instance, if I load ‘Hard Rock Kit Dry’ I see two crashes that I like. If i try to find the separate wav files in Mediabay, I can’t find them. For example, ‘CrashCymbalEdge_hk_49_062.wav’ can’t be located anywhere in Mediabay, at least I can’t locate it there. Does anyone out there know why? :question: Am I doing something wrong?
