Try plugging it into another computer or an Xbox 360 even works, see if it charges or not. If it works in the Xbox or another computer just try another USB port in your computer (Even if you computer recognizes it that doesn't mean that your USB is working functionally) another thing is if you are using a USB extender or anything of that nature unplug it and let the Zune have its own port. If this doesn't work call Tech Support and request to speak to their manager since they usually speak good English. (I would look up in the thesaurus a few words for manager just to be prepared)
