Don't worry, the answer is simple and we assure you that you're not alone. Your issues is likely resolved using one of the following two steps:

  1. Check Pop-up blocker is disabled
  2. Check minimised windows to ensure neither your module nor a duplicate login screen is open, having either active will prevent a new module opening.

The prevention of additional windows opening ensures that your progress and all assessments are recorded correctly. We would hate for you to have to resit an assessment just because you had two windows open.
