New Fuze..Error Message HELP PLEASE!

I think switching to MSC mode should allow your computer to see the Fuze as a drive with a drive letter, but if you intend to use it for subscription tracks such as those from Rhapsody you need to connect the Fuze in MTP mode. My guess is the error is probably because you need to upgrade Windows Media Player and you should do that next if you subscribe to a music service.
