No form for creating a new podcast subscribe button

I am trying to add a podcast subscribe button to my Wordpress site. I downloaded the file, uploaded it to Wordpress using the plugin uploader on Wordpress. But when I go to settings to create a button, there is no option to create a button. This is what it gives me: Title & Shorcode - No options found. Then under that it says Default Settings and gives me the option of Style and Autowidth. Then a save changes button. Nothing else at all. I hit save changes and it still doesn’t give me any type of form to fill out or anything to create a button with. What am I doing wrong? Do I have to upload the plugin via FTP? How do I use this? Thanks!

Is there no “Add New” Button?
