First, make sure that you have the correct version of Blackboard selected at the Respondus 4 “Start” menu. Next, recheck the server information that was entered into Respondus 4. For example, make sure that the login URL pasted into Respondus 4 is taken from the actual web page where you enter your user name and password, not a preliminary portal page.

If you are unable to resolve this problem, submit a support ticket that includes which version of Blackboard Learn at your institution and the version of Respondus 4.0
