[tor-relays] Cannot Access Tor

Hi I have tried everything possible following information on all the forums available and am frustrated as I cannot access Tor. Whenever I try to initiate Tor, I can see the processes running firefox.exe for Tor Browser and tor.exe but I do not get the initial pop-up dialog to connect to Tor. I have Norton Internet Security and have even deleted and reinstalled the “trusted” programs for the firewall to allow access to. Please help. Thank you
