I just did the firmware upgrade to 1.02.13 on my CLip + 4gb and it also shows Critically Low (0%), even though it has been charging for over an hour and it was up to 30+% before the firmware upgrade.

Try formatting it, and then setting it up to charge again. Just back up anything you have on it before you format it.
