IT Electric joomla template not installed with quick start demo site

Hi,
I bought the pro packagIT-Electric joomla template and I installed it in my joomla site https://webinoo.com .
.
but I can’t install the quick start demo package supplied with it to have demo images and pages.
The web site is loaded with no demo images when you visit webinoo.com .
So how to proceed please.
So I am not happy to see complicated installation.
Regards
Rabah
