I can't change the Network Trust and Device Trust under Firewall / General Settings / Network Settings. I had to do a system restore and evidently lost the trust setup I had created. When I try to set the Network and Device Trust, the software won't allow any changes. It appears as though I don't have admin privileges, although I am running under an account with administrator privileges, and did the right click to 'run as administrator'.
My product is:
