Getting a 404 when clicking to get key

I am sad to see Contact Form 7 suddenly get so complicated…used to be so easy…sigh. Anyway, I installed both extension to the CF7 plugin and when I click on Create Key on the Create a reCAPTCHA key page, I get 404, page not found. I tried with both individual and global keys. So I cannot activate the form. Please fix this soon.
