Check for updates (Help > Check for Updates). If it says you are running the latest major update but you don’t have Version 4.0.5.02 you will need to uninstall and reinstall Respondus from the secure downloads site. Information on how to download and access the license for Respondus is available in the Blackboard Self-Paced Course under the LTS Secure Download tab in the course menu.
The next step would be to check the Blackboard Server connection, since it’s change to HTTPS secure settings. Under preview and publish you tab in Respondus you can choose the server and edit the settings.
