Malwarebytes' Problem

 I have download and run Malwarebytes' 1.45, but when I try to update the files, I receive an error message.  I've contacted Malwarebytes' and was told to make sure my Security Program NIS 2010 and it's firewall is set to allow the Malwarebytes' files.  I've checked the firewall settings but I can't find where to allow Malwarebytes' files.  Where would I need to check NIS2010 to allow those update files?
