Game loading issues after purchasing and downloading Adventure Awaits.

Hello, I recently had my game update from the new adventure awaits pack that I purchased. But now, when I try to play my game, it loads but then fails, and I get this message: An error on our end caused the launch to fail. Try again later. I would wait until the next day, even, and it still won't open. I use Mods and CC, and I downloaded some new ones after my last successful game load. So I went in and removed the mods that weren't tested in my game yet, and the game still won't open. I am at a loss for what to do.
