I'm trying to get http://thevolunteerlounge.me/ to launch, but the only thing I'm getting is somewhat blank page. I have downloaded the Blackboard Collaborate Launcher. When I go to the http://thevolunteerlounge.me/ URL what I see is a page with a purple background and two overlapping white rectangles. (See attached.) I think a .collab file is supposed to download, but it does not. Running MacOSX 10.9.5 and have tried Safari 7.1 and Chrome 37.
