Help please, I have my DInc for about a week now. but as a true techno dummy I get very frustrated by what might be basic for others. I've installed the tunewiki app because I read it could help to add some missing album art work for me. I keep getting "no music found on sd card" msg whether I click on Artists, albums, songs, etc. What does this mean and how do I fix? thanks so much! Appreciate any advice offered.
