Bender 3.8 reCaptcha not working

[e9coupe]

Looked around for this problem but didn't find an obvious solution.  I added google reCaptcha in the Admin-Settings and it worked initially.  I just got a message from a user saying that it won't accept good selections on the recaptcha and I verified that it's no longer working properly.  "The reCAPTCHA was not entered correctly" is all that gets returned.  I've also updated the keys and still get the same error.

Any ideas where I should look for a problem?

Thanks,
Dan
