recaptcha v2 doesn't trust me any more

I know that this isn’t really a wordpress plugin issue, but I thought one of you might be able to answer my question anyway.

I’m using some plugins that make of recaptcha v2 (the checkbox). Before today, I could just click the checkbox and be accepted. But today it started asking me to verify my humanity by copying text, like with Captcha v1. How can I get it to trust me again and accept it when I click the checkbox?

It wouldn’t be such a big deal, except that I’m trying to record screen capture video to demonstrate how to use my site, so I need it to work the way it would normally work.

Thanks.
