Ive now noticed there are several people with this same or similar issue.
edit:
on a whim i ordered another y-cable that came today praying that was the issue but it wasn't. does anyone know if i can erase data on pc and reformat on wiiu ?
edit:
i just gave up and reformatted on pc and then back to wiiu which sucks . now the redowloading and I LOST ALL MY SAVE DATA TO ALL MY GAMES. bummer....
