I'm so sorry about that! Have you tried uploading your contacts in a different browser or a private/incognito window? I took a peek at your account and can see your contacts did upload into your account. If you need help with uploading any other contacts we can troubleshoot this further for you. You can email us at social_support(at)constantcontact(dot)com with your username, a reference to this post, the type of browser you're working in and the file of contacts you are uploading.
