My Philips GoGear Mp3 wont let me sync music to it anymore?

I got a Philips GoGear 2gb mp3 player for Christmas, and for the past two months, it wouldn't let me sync music onto it. I just hooked it up one day, and a lot of you are going to say " did you remember to turn it on?" but you aren't supposed to with this one. So anywho, i hooked it up, it connected, then i started syncing songs and then the first song failed and the rest of the sync list did too. I tried hooking it up again and it denied that it was connected. I thought it was dead but the only way to charge it is to hook it up to the computer, but it wouldn't connect. It does, however, connect to my parents computer. So after i charged i tried syncing again, and it said there was no device connected. Iv tried often since this happened and still no luck. Has this ever occurred to anyone, or does any one know how i might be able to fix it?

Thanks :)
