Apparently, I reset the password on my other account, RealityChek, and forgot it. Then, like a total doof, forgot which email I used for that account. Go me. I've got several passwords I usually cycle through when making an account somewhere, but oddly enough, none of them worked. It's not a huge problem; I can still log into the account on the game, and that's what really matters. I just thought I'd log in and see which email I used for that account so I could figure out which email I haven't used yet.
I don't suppose there's any hope for this situation?
Edit: I should mention that I plugged a few emails into the "Forgot password" slot, and one of them said it sent an email, but that email isn't receiving anything.
