Import issues with youtube videos

I want to import some Korean music from Youtube. Set everything up and when I go to hit save and generate lesson it says “failed to save lesson”. Do I need a premium account? Do I need to become a librarian? Is there some issue with importing on Google Chrome? Any help is greatly appreciated.

Yes, you will need to upgrade to Premium to get access to unlimited importing. Also, make sure that videos you are trying to import do have subtitles available in your study language (CC button on YT).
