How do I remove write protection for Lexar Secure 2

My Lexar secure 2 flash drive is now write protected and i need it to work bad! Its memory is full and i need to delete a ton of files but it will not allow.As far as i can tell it has no switch. Is there anyway i can remove the write protection?
 
Possibly do a firmware update? See if that can fix the problem.. Otherwise I would think you might need some software that came with the flash drive to turn this protection off.
