Just curious, has anyone tried Kekes solution? If so, could someone please explain when exactly you put the serial number back in? The Nero program will not work (for me anyway) without a serial number. After removing the number and changing the date and then trying to use the program, it asks for a valid serial number before the program will let you access it. Before proceeding I wanted to know if this is what is suppose to happen. Any input would be appreciated.
