New Micro SDHC card reads as empty in Clip Zip after refreshing

Saratoga, Thanks for the suggestion.  It was on auto detect, but I tried again on both settings, and no change.

I did put the card in when the device was off.

The card is a Sansa card, and is formatted FAT32

I just successfully updated the firmware, and still no change.

When I was putting files on the card, I was just using Windows explorer.  The files are in a folder heirarchy as so: Artist/Album/* *.mp3 files

I tried first copying the entire folder structure for each artist, then tried just the song folders, to see if that had anything to do with it.  Will the ClipZip read the folders heirarchy?  Do I have to just copy individual files?  That seems silly as then, i would have no filing system on the device.

Any other suggestions?
