I installed the Rio Music Match software when I got my Karma and it's been working great (I have the most recent version). Because I already had the software installed, I didn't bother to install the Rio MM software that came with my Cali. The problem is that my Cali won't show up in the player list while running the software. The disc says "Rio Music Manager Software for Cali and Chiba", but I just assumed that it was the same software that shipped with my Karma. Am I wrong? And if not, how can I get the Cali to show up in the software (up 'til this point, I've just been transferring the music via Windows Explorer).
