Pack is Gone

I just logged in to play and all of my saves are telling me they require the "Get to Work" pack and directing me to purchase it. But I already purchased this pack earlier this year and have played with it many times. Everything was fine when I played a week or so ago. I haven't changed anything. How do I get my pack back?

I've already tried managing my add-ons (it's not there). I've also already tried repairing.
