Hello, everyone!
I recently got a new Wii U to replace my old, freezing one. I figured that I could link my old Nintendo Network ID to my new Wii U. So I tried linking the account by entering my old unername, password, and e-mail, but it said that this ID was already linked to another Wii U (being my old Wii U!) I was a little confused with what they told me. Any suggestions? If so, thank you in advance! Happy new year!
