## Description

It wont download some of the video files. It happened few months ago but it still happens. Hope it can be fixed. thank you all for your work.

Edit 2019-06-04 08:09:48 AM
Please, it is broken. Downloading incomplete courses without any notice. I just deleted all of them because I don't know which one is complete and which one ain't.
