Just tried a re-install as suggested. The same error. Can someone please clarify what is meant in this article by "adding the extension manually." ? It does most file types fine, but not MP4s - just shutdown once I have dragged them onto the interface and once I click on the play button. Any help is appreciated.
Hello. I am trying to join two mp4 files but having the same error message come up. Would you mind explaining how you 'add the extension manually'? As I can't see any way to do that... Cheers!
