Pretendo Account Got “Deleted” on Wii U

For whatever reason, trying to go to a miiverse post directly from the Wii U home screen (still in the Aroma environment) caused an error message to pop up stating that something was wrong with my account and that it had been deleted. I can still use it on my 3DS and I was able to log in to it here, but if I try logging in on the Wii U, it still says the account has been deleted. Any idea how I can fix this?
