I've been in the system for months. Now suddenly my login doesn't work and it keeps popping up that my username doesn't exist. So I tried to set up another account with a username similar to it, and though I'm logged in both here and e-hentai, I'm not getting anything past "Error: No account exists with name *******. "

I'm logged in on the other sites, why is it that I can't log into this one anymore?
