Pokemon Bank Error {SOLVED}

[Duhllin]

"You previously used a different copy of this game. Please try again using Dillon's game."

I'm using the same cartridge, but deleted my previous save. What do I do?

 

Edit: I'm keeping this up for anyone who has a similar issue. The problem was not with the game I was using. It's with the game I was not using. I was trying to use my X/Y copies. But for whatever reason, I had to put in my Ultra Moon copy first in order for things to start working like normal. I am now finally able to go back into X/Y pokemon bank.
