Thank you for reaching out to the Community! I apologize for this experience you're having with adding your contacts. Are you receiving any error messages? I would also suggest trying in a different browser or a private/incognito window. If you are still unable to add your contacts after testing your browser, we would be happy to look into this further for you. You can email us at social_support(at)constantcontact(dot)com with your username, the contacts you are trying to add, how you are trying to add them (uploading a file, typing in one contact at a time, etc.), the browser you are working in, and a reference to this post.
