hi
i am new here
i have a 512 mb pocki(or aviator) mp3 player.
I downloaded some mp3 files from internet and transfered them in my mp3player, it dose not work anymore and just a blank screen appeared and it is not detect by my computer

just like a useless piece of electronics
it works with samsung chip and this text is on it's chip: "samsung 446" .
is there any way to fix my mp3player? actually i mean is there any "firmware" to reset it's chip?
thanks in advance
