tina, if you want to be daring, open the player up, this will sepertare the glass screen from the actual screen, then remove the broken pieces, as long as your careful, you won't need to worry about scratching the screen.

You can probably goto any hobby store and buy a small thin sheet of clear plastic, just cut it to the right dimensions and glue it in place.

This will have solved your problem, but if you want it more professionally done, you'll need to take it to a store, i am pretty sue even the manufacturer of the product won't replace the screen as 'accidents' such as yours are not covered in most types of warrentys.
