Well for me it did, though I have a space in my username. :)
I see that it doesn't download the audio file for it. (the video doesn't have to have audio.). I don't know the problem behind it, but it doesn't see work for me either.
What are you doing when this happens, also what video are you trying to watch?
Too everybody that is doesn't work for, move it to a directory with no spaces. Also remember to update youtube-dl.
If the directory has spaces in it in anyway, even in your username, it will not work.
All you need to do is move it to a directory without spaces.
I just found this out too :)
