So I recently got a new computer and for the first time I've been using windows media player on my 360 to play music. It worked out fine for a few days then one day I glanced over at my xbox and the artists names were disappearing one at a time (WTF!). Ever since then it says that i have no music or videos or anything but on my computer its all good. I recently deleted my user account on my new computer and made a new one because the old one was freakin out. I think maybe its still synced with my old account. Is there a way I can add a new extender or something so it's getting stuff from my new one?
