Hi all. I've istalled and activated the plugin,then i've putin the field also the api key,but appear the message "Uh-oh,you haven't a list! Please go to MailChimp,get the login and set a list befor using this plugin!" Well i get the login but i've already created a list before . What kind of command or button let me choose a list for the plugin? The plugin simply do not recognize that a list already exist.
