Computer wont show music files

I plugged the Clip into my computer, a Warning Popup appears saying that the USB drive had experienced a power surge something about greater voltage ?  I disconnected and tried again, No Warning , but now when I look to manage Clip files there are no files showing.

Yet when I disoconnect and start the Clip the music is there and plays. I want to be able to delete some albums and rip new ones. Did I fry the thing ? The  USB port still works I tried a Sana Express and it shows all music files ?

UPDATE: Reading other threads I downloaded update form Sansa. All is well. Got everything working.10-4
