I am using Win 8.1 64bit and running as admin I am unable to immunize telemetry hosts. When I click on the optional tab and try to apply Telemetry Hosts (extensive lists) I am unable to get it to actually apply. Here is the info from the log tab:

I have been unable to get past 14% protection, I have tried reinstalling to no avail. Is there anything I can do?
