Reload Halion 3 - HOW ???

Dumb question but the answer is unavailable from the dumb manual.

Under Options I’m trying to reset my Outputs Configuration to 4 / 4 / 0

Enter the numbers in the boxes and click “Apply” then I get a dialog box telling me to reload HALion to apply changes…

How does one reload HALion??? It’s not in the book…,

Thanks…,
