Unpacking the package…

Installing the theme…

The package could not be installed. The theme is missing the style.css stylesheet.

Theme install failed."

Please I need assistance urgently.
It is really Frustrating,
Hello :
I´ve managed to install the template using the quickstart file. The site pages are shown as the live preview. Everything looks fine. I just cant find where to edit the Home Page.
I´ve used other templates/Editors in the past.
If I open Pages ---> Home
I get a Page with nothing... Am I missing something?
Thanks in advance. I need an answer as soon as possible please.
I purchased and downloaded the theme, i had installed the basic first. I added my webpage address in the purchase section. The theme says installed , but there are no pre-populated pages , and the page show says free
