Thread: Problem Remembering Current Track Position???

I not sure if this is the media car causing it or my pc setup, but lets say i'm playing a long mp3 (liveset) which is 90mins long and i'm at 45mins, then i shout down the pc I turn it back on the next day and it's back to the begining of the mp3 which ****es me off because i dont wanna listen to the first 45mins againg, so guys is there something wrong with my set up, or is there a solution to this problem?
any help greatly appreciated guys
