How to add more than one forum?

I have the same issue as here: https://premium.wpmudev.org/forums/topic/forums-plugin-only-allows-one-forum#post-111755

only my forums-framework.php file is empty. I re-downloaded the plugin and still empty.

Did I miss something? Is there an easier / better / cleaner way to add a simple forum to a non-MU blog?

Thanks
Lori
