i have had a Delstar MP3 player for 2 weeks with no problems whatsoever with downloading music and my computer recognized it. but after i disconnected it from my cars radio after listening to it and after i changed the battery, it started saying "Starting....." and when i connected the mp3 into my computer, it said it was an unrecognizable file. i can't get it off even after ive put in an unused battery in and i can't access the music.

can anyone please tell me why it's acting like this and thanks
