Hardware Unable to use Plex anymore

[Noctosphere]

I don't know if I'm at the rigyht place
So yeah, since today, I don't know why, I can't read videos on Plex anymore. When I try, it ask me to reload the video, like if it's tooo big for Wii U.
Anyone has idea of what I can do? It worked very fine before, I don'T know why it stopped working
