Nero 7 hanging/freezing up

have been trying to use Nero 7 but when I go to “make my own DVD” option and try to get files to burn program freezes up and just hangs till I close .Have done a clean uninstall and tried reinstalling but does not help. Does Nero 6 decode dvd files? Anyone have any solutions?-Thanks.

You might have problem with not having proper S/N for the version you have installed.
