I finally got one of these a few days ago, and checked today and saw it was version 1.00, so I downloaded the 1.13 files from here and the SMF player from the Roland site (I'm on a Mac). Followed the instructions to the letter, and at the end saw there was a check sum error but that the operation had completed and the instructions on the unit said to wait 40 seconds before powering it down, so I did so. After turning the unit back on, the screen is blank. Despite this, I tried resending the files, but no change.
Please, please tell me there is some way to recover this. I haven't even had it 48 hours and would hate for it to be dead.
