Hi Stanley,
It looks as if you are running the Windows version of Jaksta Media Recorder.
For this query you will need to head over to the Windows technical support forum.
This is the Mac forum, and the Mac software setup and operations are quite different to the Windows version.
You can get to the Windows forum here: https://www.jaksta.com/support/windows/technical
