Using Virtual Orchestra

Thanks, please stick with me on this.
I did follow their instructions, carefully

You are right, MG lists the sample files but does not play them.

I Virtual Playing Orchestra as a folder containing folders for Brass, Woodwinds, etc. I can see the files within those folders. I still can’t figure out how to make MG see them. I’ve tried everything, over and over.
Does the VPO folder and/or folders inside it need to be in a particular place? I’ve added that folder to MG’s “scan folder” window and ‘saved’, but no good. Help, and thank you.
