I bought 400 Days in Steam, and I can't try it! When I run The Walking Dead, there's no 400 Days episode, it only writes "coming soon". In the Steam store I can see that I already bought it and there's 3$ left - that's what the DLC costs.
Also there's no folder with it in SteamLibrary, but I can't download it for one more time.
What should I do?
