fuze stuck after refreshing media

Go to the firmware thread and look for the MANUAL FIRMWARE UPDATE and the All Regions link. You need to download a .zip file, UNZIP it and drag over the unzipped file or folder. 

If you can’t get a connection, then hold down the << or center buttons while connecting.

Are you sure your Fuze is Version 1?  You can also try installing version 2.03.33 . Version 1 and version 2 are different hardware versions and the  firmware will only install in the correct device.
