The Sims Legacy Collection

When I launch the game, I get a popup for The Sims Unleashed and have no way to actually close it. I can't scroll, there's nothing to click. I have changed my resolution prior to launching in the hopes that it would change anything but it doesn't. Has anyone seen this yet or have any suggestions on what to try? I couldn't find a topic when I looked just now, but I also am a little stumped on what to even search.
