un-block in killswitch

How do I un-block a blocked service I had blocked unintentionally in killswitch? please help

Right click the process and select “Add to Trust Files”.

You will find the blocked program buried under CIS’s advanced settings > Security Settings > Defense+ > HIPS > Protected Objects > Blocked Files. “Remove” it from there.

Thanks, but I had just uninstalled CIS completely and reinstalled an older version of the process that I had unintentionally blocked. After reinstallation of CIS I am now having difficulties in trying to load CIS at startup automatically. I am now going to try and uninstall, reinstall, once again.
