This problem could be due to Apples new security features. Make sure you have allowed LiveReplayer to use screen recording.

To do so, follow these steps:

  1. Close LiveReplayer if it is running
  2. Open System Preferences (Click -menu then System Preferences)
  3. Open the "Security & Privacy" settings
  4. Scroll down to Screen Recording and click on it
  5. LiveReplayer should be in this list and with a checkmark. Unlock to make changes by clicking the lock icon if you need to.
