ReCaptcha worked yesterday after installation - today it doesn't

Hi.I successfully installed the new Google ReCaptcha API yesterday and tested it locally on VS2012 before uploading it to my website. It worked on both and I was very pleased. I get up today and it doesn't work on either! I am shown the dreaded 9 pictures and told to choose which one has eggs!The ReCaptcha support page says 'There are one or more of the following reasons why it occurs:' Your browser is old (see minimum browser requirements). Javascript is disabled in your browser. Some of your installed plugins conflict with reCAPTCHA. Unstable network. Tried it in 3 browsers, all up-to-date. Still no good.I have JavaScript enabled.Temporarily disabled all Plugins and still no good.Doesn't work locally or online so can't be network issue?See app at http://bit.ly/1IQ6oQp, any suggestions?Many thanks,Nick -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
