Using reCaptcha with Pro

I’m not sure how to get this to work.

I’ve purchased the pro version- and I have the installed number captcha thing working/showing.

I’ve been to http://www.google.com/recaptcha and acquired the public and private keys.

I’ve entered these keys into VFBPro settings.

But I don’t know what to do next?

Thanks for any insight that I’m obviously missing. And I know it’s me: I can’t find obvious if obvious is sitting in front of me. lol.
