SONAR protection and Calibre

I have been using the eBook conversion program Calibre for a year or more. Since upgrading to NIS 2010 and the latest Calibre 6.4, NIS objected to and instantly Quarantined Calibre I chose to restore and ignore - I had to do this 3 times before NIS finally ignored it.

 

I have been asked to replicate this but I can not find a way to Un-ignore this program in SONAR or any details in History of the actions.

 

(I am totally satisfied Calibre is not a threat).

 

Help anybody?
