I did this programme a disservice when I put my first review on-line, since reading the review from acat550 I downloaded it again after clearing everything belonging to Nero off of my computer. I think that something mught have gone wrong while downloading it originally, as now it works perfectly and I can add my own pictures for the background which is great. So apologies to Nero it does work and very well and is a good substitute for Nero 9 which stopped working and then wouldnt open after downloading an upgraded version. so ignore my first review. And to bensiton contact Nero.com and you will be able to purchase this product and get the serial number you need.
