NIS 2010 File Insight ,Trust Now option missing

Where is this option, button, link, TRUST NOW, it is nowhere on my File Insight window with details open!

 

The text of the help file says

 

"To manually trust the file-

 

In the File Insight window, click the Details tab to open it.

 

Click Trust Now.

 

You can manually trust the files that are not trusted, poor, or unproven."

 

The help file says there also should be a "Check Trust Now" button that I do not see.
