Stuck in Upgrader etc

Hi Folks.

I was given a Rio Carbon as it was not working. I have other Rio products. Anyway. When I first plugged the Carbon into the USB port of my computer, the battery charge display showed for about a minute, then the display showed the Rio Logo. So far so good. No lights come on at this point. Then, the display changes to the word "Updater". I have run a variety of firmware programs that are for the carbon (found them on the Rio site and others.) and they do see the Carbon, but display the firmware as version 0.0. A few times the program has returned that the update did not work and does not state a reason, but most of the time it says it was successful. Then, the Carbon reboots and does the same thing as listed above. I've left it plugged into the USB port over night and tried again, and still get only the Updater sign, but no longer see the battery charge display.

I've booted while holding down the reset button and power buttons at the same time. Still no luck.

When I go into Windows XP Explorer, I can see that the Carbon is there, but when I click on it Windows asks me to "Insert a disc into Drive F", which would be the next drive.

Is this Carbon better off as a door wedge than attempting to make it work? I'm willing to take it apart if something would help such as perhaps a loose connection.

Thanks for in advance for your help!
