I think I screwd up my player.... tried editing the firmware with a hex editor, and uploaded it back on...now the player is stuck on the blue screen with the hourglass and doesnt do anything else. Windows can detect some USB device as USB2 (FS) ADFU Device, but no drive apears in "My computer" and the firmware upgrade tool cant "recover" or reload another firmware.
I guess i killed my MpxPlayer

if anyone has any suggestions just psot a reply
