Cannot install / use ?

Hello!

Please help me to run this thing.
I have installed the plugin:
http://catchline.fi/support/SP-installed.jpg

How do I update it?
Where is the admin settings of this plugin? I have browsed through the manuals, and I have not found any information of where it is..

Then, here is the page I created, see:
http://catchline.fi/support/SP-page-created.jpg

The shortcode is correct. Still, I see nothing on page:
http://www.voitelukeskus.com/?page_id=3505

Do I need to upload something more to my word press site, even I have succesfully installed the plugin, just like any normal wordpress plugin?

Help me.
Pekka
