KeyError: 'cipher'

I am using the latest version and got this error

 c:\Users\iball\Desktop\yo_downloader>py test.py
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

I noticed i get this issue when youtube claims the video has copyright problems, i hope this helps solve the problem.

ya but that's not the case with me actually. I tried other downloader for same video and that's work.

I'm getting that same issue today. Also tried with a link embedded on a website and I can't play it back there either.
