“Downloadable content not installed”

I know a lot of people are having this same problem as me but I’m not quite sure how to fix it. I recently downloaded the game and I made it past “The final test” but when I went to go play “The showstopper” it says “get access” and when I click on it says “Episode 1: Paris. You do not have the required content you need to get Episode 1: Paris.” But I have already installed everything. If anyone knows what’s wrong or how to fix it can you please tell me
