how can i fix my creative zen micro mp3?

After charging my MP3 player, the screen seems to be locked on to a screen displaying the "creative logo". I cant seem to get past this point to access any of my music, plus I am unable to switch this on and off or use any of the buttons.

The only way I can switch this on or off is if I take the battery out. However, on putting the battery back into the player you still seemed to be locked onto the screen displaying the "creative logo".
