Homebrew Error with Smash EUR dlc

[guiguinha]

I did homebrew and everything worked, now when I download Smash dlc it works fine, but when it passes like a day it says there is an error with add-on content (p.s.: Mario Kart 8 don’t work at all

Question 1. How have you modded your Wii U and which guide did you use?

Question 2. Where have you obtained the DLC from?

Question 3. Have you installed the relavant updates required for the games?
