When Hitfilm Pro opens, it always opens with the same message, "Another instance of Hitfilm is already running. Only one instance is allowed at a time." I click "OK" and it doesn't open at all. How do I fix it? Thanks.
maybe this helps.
@starrynight25 restart your machine. Alternatively you can stop every HitFilm process and then you'll be able to start HitFilm correctly.
It looks like what it says: There is already an instance running. Check if Hitfilm is running in the background, look at task manager to find out if you have a hidden process called Hitfilm oder Hitfilm render Client.
I got that sometimes when Hitfilm did not end correct and stays as a hidden process.
Movie Studio has done that to me , when it would "Crash during Exit" . leaving a Movie Studio process running .
The real problem is , why isn't Hitfilm closing all of it's processes ? for you . Did Hitfilm ever crash ?
@humptylumpy in truth, this is a long standing Hitfilm issue. Sometimes it doesn't exist cleanly, leaving a media server process running in the BG. Seems the process sometimes takes a couple of minutes to close. Using Task Manager to kill the process works.
