I have not tried the invisible captcha just yet. However I have not been able to use older programs using recpatcha because I keep on getting errors. When I try to login to the site for register I get invalid captcha and they keys are correct. This happened to me with wpdating plugin and also elgg social community software. I receive a error that says invalid image like someone is tampering with the image. Can anyone help with what this may be.
Thank You Vinny
