Same thing happened to me. I had made a new large photoshow using my purchased home software NERO photoshow v5. I was trying to finalize the photoshow I had spent hours working on. NERO kept shutting down due to unexpected error. Finally somehow I ended up connected to the ROXIO website which said NERO no longer works and I had to upgrade & pay $29.99 to get premium account and access to my photoshows. I did this but lost my unfinalized photoshow...pain in the ,,,,, since there was no upfront warning and no email saying this was going to happen to NERO customers. Anyways had to redo entire photoshow. Was able to burn one DVD and no others until I downloaded version 6. Burnt 2 photoshows and now cannot burn another one. Came to realize NERO and ROXIO were generating files hidden by Vista and had devoured 30GB on memory on my laptop. After finally finding these files on our own since tech support had no idea of what I was talking about I deleted the 75,000 files and recovered 30GB of memory but now cannot burn a DVD. WHY NOT????
Nothing works easily and I hate the day I met NERO photoshow.......and so does my laptops memory.
Anyone else out there experienced this??????
