Was there a popup that if there was and you said block is in web and email protection/Firewal/internet conections for programs. Unblock it there for firewall and netguard if it says so there..
Or did it detect the program as a virus and place it in quarantine are. see navigation and quarantine and trusted items listings there
There was a popup saying, allow this program to get access for Internet, or something like that, and I clicked block the 3 times it showed up. It isn't in Net Guard, or in Quarantined and Trusted items.
