Until last week I had Nero 7 Ultra Edition and it suddently disappeared. The program came pre-installed in the computer, so I don´t have a license or the original disk. How can it simply disappear? Could it be a virus? The c: folders are there, but all the files simply vanished. I even have the tag in my programs menu, but it´s empty. I am totally clueless as to how this can happen. Does anyone know?
