Is there some kind of lag between account creation and being able to login? I keeping trying to log in and it tells me my info is invalid, I've checked it all and it's correct. It's a PW account and I'm using account name.
Did you check your email to see if you received an Account Guard activation code? Generally you can't play the game until you've entered the numbers the email sends to you. Also keep in mind that logins are case-specific. If you accidentally used a capital letter in the account name or password you're always required to use it - but I'd check the Account Guard code email first.
