Hello! I'm fairly new to the SL world. I've been having quite a bit of touble logging into the viewer. It keeps saying "requesting region capapbilities" and tries three times then takes me back to log in. I know I have the password correct. I have Windows 10, AVG Security, and have allowed the viewer to communiate through the firewall. While at home, I had no trouble logging in, but It takes three tries and gives up whenever I'm on my dorm's wifi. How could I fix or get around this problem?
