Plugged the rio in and it stopped after the animated rio logo came up, pulled it out and plugged it back in and it came up with the normal starting screen, but stopped on "building database"....worried now...eventually came up, no playlist and then would reset! Yeek!

Got to work, opened it up and a jumper fell out, turns out it'd fallen off my secondary drive and both were now trying to be the master! Put a new jumper on (snugger fit) and hey presto, back up and running.

My heart skipped a bit!
