Hi, i noticed last night that all of my media files (except for paid ones from iTunes store) disappeared. I tried rebooting, then a hard reset, but no lick with either. The only away I could get them back was to respring through terminal. I now have duplicates of my paid media for some reason, and was wondering if anyone could explain this for me, or tell me how to prevent it from happening again. Thanks.
