The best way to solve it is to completely uninstall the Nero version you have and then install the full version of Nero 6. That did it for me when I had the same problem. If you buy from a reputable dealer on CD you should be able to take it back if it doesn't work. It's worth the investment as you get many other tools included such as DVD info tool, a sound mixer, a media player, a DVD player, a video editing suite and DVD authoring all in one. You are also then able to download all updates - you should download the latest update after installing.
