Hmmm, there is a workaround for this problem, there's a tool and .doc file on drivers CD that came with ur mp4 player. I got that error every time a flashed my player with new fimware, ofc the tools for unlockin it is on CD, I did it many times and it works fine. If any1 needs it I can upload it somewhere along with original firmware for my MS Industrial MP404.
