Adventure Awaits appears to be unavailable

I went to boot my game today to find that adventure awaits isn't working. 

When I try to load my save it says "Requires Adventure Awaits". When I click view packs its says that "This pack is unavailable to purchase" (even though I already have it). It also says that restart is required but I'm not sure how to do it and if it will fix my dilemma. 

Please help!
