If it isn't cooperating then you might want to uninstall it then reinstall the Firewall. If you have a couple of Symantec programs you may need to uninstall them both--sometimes they get out of sync otherwise. (And sometimes when you have to reinstall them the clock starts all over as if you just bought it. This doesn't always happen, but sometimes.)

The benefit of reinstalling the program is that it will once again set up the rules to allow everything you already have in there, and your new viewing program should work fine.
