I have been using Go To Webinar for a few years now, and I never had any issues. Now I cannot get into my webinar, no matter what I try. It just says "Connection Failed. Please check your internet connection and try again." It does not matter if I turn my firewall off (!) or anything. It just does not work. I have great wifi at home and at work. I have tried 3 different laptops.I have tried multiple browsers. Nothing works. I have an important webinar tomorrow and I cannot get in. I really need some help. Thanks!
