My husband uses Photoshop Elements 3.0 and managed to lose/throw away the disc folder that had the product serial number on it.  Of course he had no copy of the number anywhere.  It's still installed on his system and usable but does anyone know of any way to retrieve the product number?  If he ever has to do a reinstall or a system rebuild he can't reinstall the software without it.  Any suggestions?????

Help,
