Hello Wiilink!
I have issues with the demae channel. I reinstalled the food channel, grabbed a new download, reinstalled adress settings, and checked my connection. All have failed to make it so I can order on the demae channel. Attached is a photo of the error. I don't know why it has been down for so many people yet wiilink hasn't announced it is down. I am using the demae channek through my vWii on my Wii U btw.
