I just fixed my related problem were I was unable to play ttk after purchasing the digital collectors edition. By following the information in the below. clean out your cache and re-download your purchase. Then when you are finished restart the game. I hope that helps. P.S you will only have to re-download the new content not the whole game with expansion packs.
