I’m not sure my theme is calling wp_head(). Can I check?

Yes, you can. In the Dynamic Widgets Overview page, click the Advanced > link at the bottom. You should see if wp_head() is called in your theme. It is possible Dynamic Widgets can’t detect if the theme is calling wp_head(). Please contact the author of the theme to ask for it. You can also of course just try Dynamic Widgets to see if it works.
