Hi @pulloutthecoupe.
When you've got a chance can you try resetting the password for your EA Account to see if that helps? That can sometimes fix the invalid account error. For more info on how to reset it check out the EA Help website.
If you're still getting the same error message after that please reach out to the EA Help team so they can pull up the account and take a look. You can find more details on how to create a case with them over at the EA Help site. If you prefer you can also speak with them via Twitter or Facebook as well.
