NHK Easy Course Not Updating

Around the middle of last month, I did one of the lessons from the NHK Easy 2018 春夏 course. Since then, no new lessons have been added. Is there a new course somewhere? Or do I need to use the code provided to keep it updating? Please help because I’d really like to use up-to-date news lessons.

That course was imported by user avolkmann so you can contact him on his profile wall and check if he plans to import more lessons.
