I can't sign into icloud?

[iMore Question]

I didn't forget my password or email but I can't sign in? But when I try download a game or update one I can't because I can't sign in. On the App Store it tells me that my account still exists but after doing further research it tells me that my account doesn't exist anymore? Can anyone help me please?
