I have two macs in our institution that have the same problem. When you are in a course and click Course Tools and Blackboard Collaborate Ultra, it spins and then says, "Uh Oh! It looks like your login session has expired."
Here are specifics:
-Latest Java/Flash - I tried adding bb to exceptions, have cleared cache
-Any user profile, any login name
-Not every mac in the institution does this
-Multiple browsers, and all settings on browsers are the same as macs that DO work
-I have installed the collab launcher
-Users can go to a different mac and it WILL work under their login name
I have spent far too many hours trying to figure this out. Any help would be wonderful!
