Why I need to downgrade: viewtopic.php?f=265&t=153488&p=402225#p402225 .

I already downloaded a version from 2015, replaced the EXE files in the KDEnlive settings with the old versions, and I am still getting the depracated (deliberate misspelling out of disrespect to Anton Khirlov's favourite word) errors?

I would appreciate any help to bypass the obstacles that rogue developer put us in the way.

Please excuse me for being so heated.
I likely suffer from A.D.H.D. .
