Is that Gmail account the same user name as you are using with Google Talk? I note that you have a password reset in progress there. I expected a password reset message to be in your secondary account - there's no point in sending a password reset to the same account because if you can't sign in, you can't access the reset message.
Have you recently enabled two-step verification for your account? If so, you need to use an application specific password for Google Talk. If not, then you should try clearing captcha as in: |
