Incomplete download

[chaffinched]

Hi, I've used udemy-dl and coursera-dl, so thought I'd try this. I don't get any errors, but from what I can tell only about half of the videos download. Those that do get downloaded are complete.

None of the articles download, although I think that they are being presented differently than before, which may explain it. As an example, forensic-psychology 4 downloads 14 of the 35 videos and nothing else.

Thanks for your work on this so far. If you want me to try anything, just ask.
