Problem with Re-Captcha

Hi,
I’m the developer of http://www.calellanight.com and I have an answer. I put the plugin in my page with RE-CAPTCHA I logout and now I can’t enter the page said:
To use reCAPTCHA you must get an API key from https://www.google.com/recaptcha/admin/create

Now I create a RE-CAPTCHA in Google, but I can’t enter and I have the admin account.
I need a faster answer.
