I need help here, too, but for a different reason. I just started SL, so an update change isn't the issue. The voice chat doesn't work, definitely firewall caused. Thing is, when I tried to click on the allow button, the whole pop-up window froze up, so not only did it never take, the window vanished on me. I tried to find other ways to get it to allow the program, but no go. However, my Firewall is Windows Defender, so the articles above don't help at all. I tried calling my ISP, using the port numbers that were on the notice message, but without the full IP and codes, they won't do a thing. I tried looking up that information on here, but found nothing, I need the Voice chat running, because I'm a singer...or rather, will be one if I can get discovered. Please help.
