In chapter 5 I can’t reproduce the videos, what’s wrong?
I presume you mean ‘can’t play’ when you say that you ‘can’t reproduce’ the videos? Since there are potentially many issues that can cause a problem, you need to give a lot more information here for me to help, For example, to begin with do the old lectures still play correctly? If you go to YouTube, to the lectures play correctly there? and so on…
If you can clarify your problem, I’ll try to help. Good luck.
Hi DHz I mean play the video, when I got in the chapter the screen of the video was blank.
But now I know that the problem is with my PC, the youtube channel is blocked in my office.
Glad you figured it out. Good luck.
