Consider the following items when troubleshooting this issue:
- Make sure you have selected the "user personality" in Respondus that matches your learning management system. For example, if you are using Blackboard Learn 9.x, you can't have the D2L personality selected.

- Make sure that you are running the latest version of Respondus. Go to Help > Check for Update to see if you are running the latest version.

- Make sure your connection to the Internet is working properly. (Open a web browser and go to a couple of web sites to check this.)
