Purchased packs won't show up

I downloaded 3 game packs in a bundle from the spring sale, one expansion, one game pack and one stuff pack. I checked and it says they're all downloaded but they're not showing up in game. I've done everything I could at this point. I've repaired the games, uninstalled and reinstalled, cleared the cache, removed my mods, restarted my computer... I just don't know what to do. I just want my packs to work and if they don't, I want a refund and then I'll try to repurchase.
