I recently purchased this player off of, yup you guessed it Ebay! Just got it 2 days ago, connected it to my pc, put my music on it and one video. Then that was it, this morning I tried to put more on it, music and video, but everything I put on it gives me an error when I try to play it. All the files I had put on the day before still work, but nothing else I try to add will work. Please someone help me
