@EricLNZ time does not fly that fast even though these days it often feels like it 😐. It happened around late July/early August 2020. For a while after that you could ask MAGIX sales if you wanted to buy it but that option was dropped towards the end of 2020. Some early discussions linked in this comment.
Yes. My DVDA starts the rendering process (project with menus) and then suddenly stops with a warning message saying that there is an error of an unknown nature. How can I determine the cause of such a process-stopping error? I uninstalled DVDA and then re-installed it, but that did not prevent the error message from coming on screen during the rendering process.
