I recently purchased a ND5XS. I downloaded the free trial of the dppoweramp, although I've now purchased it. When I ripped my first 20 or 30 cds, everything worked great and I was listening to music. But then I tried to get fancy and changed some settings in--gawd, somewhere, which led to losing all my music on my Naim app. So I uninstalled the dppoweramp and purchased it. My music is still on my computer--in music--but I can't get anything back on my Naim app to play it. Somehow the app isn't accessing my computer files. Any thoughts? As you might guess, I'm just learning my way around computer audio.
