I have a Samsung YP-K3J mp3 player which i got about a year ago that had been working well until about a month ago when windows media player was not detecting it in the sync section anymore. I checked the device manager and my mp3 is described as an MTP Device. It had a yellow exclamation mark beside it. I don't know what i should do to get my computer to recognize my mp3 but i would like to get windows media player to recognize my device again. (I'm running the latest windows media player).
