I have always set up my system to keep old versions due to past problems with new versions. But I woke up to see all my versions from CS6 with encore for creating DVD gone and 2021 installed. I am trying to install the older version and they are not showing up. I will try system restore to days back and see if I am lucky. On the latest Adobe installer the previous version only shows 14.9 making it impossible to install older versions.
