Include "archives-calendar.css" from the plugin. Uncheck if you copy the CSS code to your theme's style.css (recommended).
NOTE: if you have modified the default CSS file it will be restored on next plugin update.

/>
Include jQuery library into you theme. Uncheck it if you already use jQuery in your theme.
NOTE: jQuery is required to be able to change archives year, elsewhere you will only see the current year.

$(document).ready(function(e) {
	$wearein = $('.calendar-archives .current.year').attr('rel');
	$('.calendar-archives .prev-year').on('click', function(e){
		e.preventDefault();
		$('.calendar-archives .year[rel='+$wearein+']').animate({opacity: .5},300);
		$wearein -= 1;
		$('.calendar-archives .year[rel='+$wearein+']').animate({left: 0},300);
	});
	$('.calendar-archives .next-year').on('click', function(e){
