alexelia on "Easy Nivo Slider doesn't work?"

HI guys

i installed Easy Nivo Slider on my WP site http://musicanueva.es but it doesn't work...

I see the preview of the slider but no way I can put it on my homepage...
In the widget space I only have 'nivo slider for current post' and 'nivo slider for post type'.

any help to insert the slider in the page?
