I just tried a different USB port it didnt freeze but that happened befoure to, so it may just freeze in a few days. Like i said: it comes it goes.
Didnt had this problem earlyer tho. It started few weeks ago and i bought the player half a year ago.
I mean eather if its the problem with the USB port, and i have to change, its still something you should consider fixing, arent you?
