I apologize there's a link in your account that is not working as easily as it should! Where exactly is this link located? Are you having this experience with the Social tab of your account? And if so, which link is it? Is this link not working for you in more than one browser or even a private/incognito window?

I am trying to create my website. when I click create your free site ! it doesn't work (keep blinking)
What browser are you working through? We have seen cases where the Builder page does not load, specifically in Safari if Prevent cross-site tracking is enabled in your browser. In these cases we suggest clicking Safari > Preferences > Privacy > if Website Tracking: Prevent cross-site tracking is checked deselect it and try again. Website Builder also has this help article with more potential workarounds.
