Log In Issue

Our customers are experiencing some problems logging into our Adobe Connect meetings.  What happens is they click the meeting room URL, choose the ENTER AS GUEST option, type their name and click ENTER ROOM.  Then the screen flashes white and they get brought right back to the log in screen.

We have tried a number of things to resolve this issue, sometimes they work, sometimes they don't:  CTRL-Click ENTER ROOM button, change the browser, copy and paste the URL into the browser, change the privacy and security settings, install the Connect Add In.  While some of these things will work (most notably changing the browser) a lot of our customers just can't log in.

This starting happening right after the the last Window Update right around July 20th or so.  Before then we NEVER saw this issue and now we see it with every webinar we run.

I would love to hear any advice, workarounds, etc.  I have contacted Adobe support but they have been mostly un-supportive.
