Cause: Licensing Warning for Reports
This message is displayed when you are select reports within the Manage tab that has more responses than the current user(s) is licensed for. This can we caused either by insufficient seats on an instructor account as well as lack of student licensing. The Reports will only show results for those that are licensed correctly or up to the amount of seats the instructor currently has.
Resolution: Update the amount of seats on an instructor license by contacting your Account Executive or see which students appear as inactive and have them license their accounts.
