Error when using "subscenter" in windows

[shlomiLan]

I have tried to use the "subscenter" provider by running this cunfigurtion: subtitles = download_best_subtitles(new_videos, set([Language('heb'), Language('eng')]), providers=['subscenter'])

But I get the following error:

I'm using subliminal==2.0.5 I don't get the same error when I tried to use "opensubtitles". What am I doing wrong?
