Still seeing the OLD ReCAPTCHA, not the new one

I've been using ReCAPTCHA for some time with my website and until recently, it worked just fine.Over the past 8 months, I've seen a huge surge of robotic spamming machines which defeated ReCAPTCHA.I was excited that Google stepped up and changed the ReCAPTCHA system to better defeat these robots;HOWEVER,I am still seeing the old ReCAPTCHA sytem on my site -- not the new ReCAPTCHA system.Need I do something to activate the NEW ReCAPTCHA service?Thanks for any assistance in this matter. -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
