WYSIWYG Button has no dropdown

So I installed the Buttons Shortcode and Widget. I opened up the visual editor and there was indeed a little button just like you show on your instructions. However, the dropdown from this button is not dropping down. I click on the editor button and there is no dropdown at all, no option to click “button”, no other option. It just looks at me and laughs while my cursor sits in the edit page box.

So, is there a secret handshake I can use to find out how to make a single, link button for my web page? Can I be sworn in to the secret society?

How do I not only put a button on my page, but also edit the size, color, text, etc. that the information page describes as being an easy interface in the WYSIWYG editor?

You have no idea how many hours I have been searching and searching forum after forum for one little button. (Most of the forums that address this are closed and years old. I copy the codes and put them in the text editor and I get code on my page where I want my button to be)

I am not a coder.

Please help. Thank you.
