Shortcode does not seem to exist.

Hi

I am trying to use this plugin, but after creating the testimonials, I do not get a shortcode option showing anywhere. I have seen some tutorial videos, and know where it should be – but nothing. I tried just putting in [woothemes_testimonials] and while it does show the testimonials, it shows all of them, not just the one. I can not see an ID for the individual testimonials.

Can you please help
