It will not let me load 1.04 firmware for my Plexetor W1210A

[Jeffrey]

I am pretty sure that I downloaded it from a post on one of the forums here. I ran the program, loaded W1210A104.bin, clicked upgrade then in the area where the percentage thing is it says, "Upgrade failed (sense 70 02 3A 01)

So does this mean I am screwed and I can not make back-ups of my games? Or am I doing something wrong that is fixable.
