We're happy to hear you have reactivated your account with us! I can see you are now under an open and active account because of this. While we do not have an available desktop app, using login.constantcontact.com is the website we would suggest using to login. What is the website you're going to? Have you tried logging in through a different browser or even a private/incognito window?
