I can't get the plugin running

Hello.

I installed the acronix shortcodes plugin for WordPress.

I have used other shortcode plugins in the past with clicking Button on my wordpress editor while writeing a post to insert items.

But now I don’t have such button in the menu. Any advice?

Thanks in advance for any answer.
