OK, I have this MP3 player, I have been relatively happy with it, until gradually, certain songs wouldn't upload to it. It would say it uploaded it, It would do it mega quickly, but when I looked on it, it wasn't there. It was always the same songs that did this. Slowly, more and more songs stopped working. Until, quite recently, MusicMatch Jukebox now thinks I have a Philips Nike, not a philips Go-gear, and when I try to add any tracks at all, They don't work. I put them in the right directory on my MP3 (_System > Media > audio) And My PC can see them, but I can't see them on my mp3. I formatted my MP3 player, but It still didn;t work, and now I have an empty MP3 player and I can't add any tracks.
Ok, I fixed the problem, I downloaded MusicMatch Jukebox 10 and then it read that I had a Philips Gogear instead of a Philips Nike, so then it worked and the songs play now =]
