This is a issue that's affecting many people, myself included. There are some various other posts around the help forums that you could find. I'm sorry I can't link them as I'm not at my PC, using my fone. People have been asking this and other similar questions for 4 days and we haven't gotten a real response yet. I'm ps3 and cannot purchase the standalone TTK content. Let's keep bumping and asking until a satisfactory answer is offered!
