I am trying to set up Sync for the first time. After putting in an e-mail address and password, entering the "captcha" words, I click "next," and instead of successfully completing the setup, I get a message at the bottom "Sync encountered an error while syncing: Incorrect account name or password. Sync will automatically retry this action." How could these be incorrect when I just created the account?

I have tried changing the password, deleting the account and restarting the whole process, but it always comes back to the same problem.
