Sorry, I know the rules say not to make a 2nd account. I had no choice. I know the email and username I used on my old account which is this -
user/ValethaNekik

But it says they are not recognized. The account hasn't been shut down since I can still view it and I would really love my critters back. I put in the username and email and it doesn't recognize them or say they are correct and I'm not sure what else to do. I worked hard to get where I was a couple years ago and I'm interested in at least having access to my account.

Any advice?
