Im trying to upgrade my mark2 from b7 to b11 by serial. it goes through everything fine and then it says finding pump device and site there forever. then it gives me an error that bad pump or something. i even tried manually restarting it during that stage but nothing. can someone give me emplode beta 7 so i can flash with that and then upgrade again. i dont want to go back to 1.03 becuase then ill lose all my marked files and how many times i listen to each track right? or am i wrong? any help?!?! thanks
