Lesson videos not playing

Hi All when I try to practise with the lesson videos I get a message the video cant play here due to its privacy settings,(lesson 4 module 1) they worked ok last week not sure whats changed (my end I sure)

Definitely something on your end as they play fine for me. Take a look at your browser settings, or perhaps your YouTube settings if you have an account. (Justinโ€™s videos are hosted on YT.)
