password error?? (when saving data)

so when I try to save a sound on my mpc it brings up this password screen.
I bought the mpc off a guy on ebay
it says password error when I enter something obviously becuase its not the right password.

Is there a way around this so I can save data onto my flashcard?
Otherwise I'm just going to have to save data onto my macbook via usb


thanks!

download the JJOS3.08 (FREE) from here: http://www7a.biglobe.ne.jp/~mpc1000/kazoechao.cgi?url=http://www7a.biglobe.ne.jp/~mpc1000/mpc1000_jv308.bin&name=MPC1000

the problem is the guy installed the one that costs 50$ and he did not register it, so you won't be able to save unless you put the free version on, or pay the 50$ and get a password from that website.
