I believe my Acrobat Pro DC (Windows) has auto updated and I cannot now access Pitstop Pro tools (or indeed other plugins).
I have tried the Enfocus workaround i.e. turning off 'Open documents as new tabs in the same window (requires restart)'. However, when I turned this option off, closed Acrobat, restarted Acrobat and went to turn on the above option again, it is already on.
Any suggestions? I am running Acrobat Pro DC 2020.013.20066, and Enfocus Pitstop Pro 2019.
