My Delstar MP3 player/voice recorder wont come on. I changed the battery and it said STARTING. When I took the battery out and put it back in, it wouldn't come on. I turned it on, and it went to the last song I listened to, like always. I pressed the play button. the song started playing, then it cut off. what could be the problem?
