Unable to log in with new Square Enix Account

[kithyen2012]

So after almost a month of trying to get this game to work I finally got it to work thanks to an awesome soul in the Windows 8 thread.

However in trying to register a new SE account so that I can two box from my laptop/xbox my new account keeps telling me I have the wrong password/se combo. Registration went fine and I can even change my password just fine, but when I finally try to log in it still tells me my password or SE ID is still wrong.

Nevermind....I'm an idiot. Disregard this :P

Yeah, I did just that Chris and I know all of my details are correct but to no avail.

Would me having played FFXIV have done anything to upset it?
