Whenever i boot up my wii u it gets stuck on the wii u menu loading screen for ages, it was 15 minutes before i gave up, ive tried rebooting but it doesn't help, it was working fine yesterday i haven't downloaded any new homebrew, only a copy of new super mario bros U through NUSspli, i do have a custom theme but using the newer method usind sdcafiine so i'm not sure if maybe that's the cause? any help on fixing this would be great, i'm using aroma if that helps at all
