Appointments+ won't show the next month, or week or anything next

No matter what I try, I can't get the Pagination to work. It won't show next month. Here is the code I am starting with, which is directly from one of your blog posts. Also, there is no shortcode menu item anymore, and I could really use that! Where are the shortcodes for this plugin listed (with arguments?)
