For some reason, I can't load videos in Law School Prep and the "Next" buttons are not showing up on the lesson pages anymore. I bought access yesterday and completed some lessons normally, but today, it isn't working correctly. I've tried refreshing the page and logging out and logging back in again with no success. Also, when I am trying to view the lessons, the "Upgrade" button is appearing at the top of the page. I have already bought premium access, so I don't know why that would be there.
