Nevermind, I disabled my firewall filters and set DNS to auto and then the update started automatically for the game. I thought it already updated, but must have only downloaded/installed the DLC. Weak Sauce!
My Wii U is still on 5.5.1 and I bought the DLC on the E-shop and now whenever I run the game it says I need to update the system firmware. Anyway to bypass this issue without updating. I know I am not going to update, but it sounds like some of you got it working with 5.5.1 and the latest...
