Cannot create PowerPress Subscribe Page

Hi

I’m very new to podcasting, wordpress and the PowerPress plugin, so please forgive any lapses in etiquette. According to the blubrry web site, I should be able to create a subscribe page from a template by following these instructions:

To create your page, go to PowerPress settings and select the “Appearance” tab. Under the Subscribe Page settings, click the link “Create a subscribe page from template”. This will create a new static page in your WordPress site using our recommended template. Do not forget to click save.

My problem is that I cannot find the “appearance” tab within the PowerPress settings anywhere in my installation of wordpress.

Can anyone help?
