It deleted all my music and has been stuck on the startup screen for 2 hours!

So I turned on my Clip Zip this morning and it took a little longer to startup. Once it was on I went to put on a My Chemical Romance song and it said all my music was gone. So I plugged it into my computer and my computer wouldn’t recognize it, even though it usually does. When I ejected it, it turned off. I tried to turn it back on, it got stuck on the refreshing media screen for 20 minutes, until I performed the 20 second reset. Now, it’s stuck on the startup flower and it has been for the last 2 hours.
