https://secure.square-enix.com/account/app 's password recovery mailer is currently broken and mailing large strings of text in place of URLs. Yay.
Are you using GMail? I had the same issue, contacted POL and they said it was a known issue, they also said its not their problem, that it is something to do with the way GMail receives emails from them.
Ask them to change your SQEX Account email address and try again. I did, works fine now.
