Help, something is not working

[microeconomy]

Hi! I don't know much about the technicalities of coding, I just knew how to use your app to download my video lessons until it's not working anymore. Whenever I try to download a lesson these messages appear:

Downloading /content/Skillshare/jakebartlett/the-ultimate-guide-to-shape-layers-in-adobe-after-effects/01 - trailer.mp4...
[==================================================]

Traceback (most recent call last):
File "/root/.Skillshare-DL/dl.py", line 16, in

File "/root/.Skillshare-DL/dl.py", line 11, in main
dl.download_course_by_url(course_url)

File "/root/.Skillshare-DL/skillshare.py", line 72, in download_course_by_class_id
raise Exception('Failed to read video ID from data')
Exception: Failed to read video ID from data

I don't know what happened. I hope you can help me.
