League News k2 style copy

Hello,
i wanna ask if i can use the style attached in this post in publisher template, if i can, how?

I use The publisher with j3.0

Hi, from : gk_league_news_J!30.zip file copy this folder: gk_league_news\html\com_k2
and paste into your publisher template using FTP.
This should works for all K2 views/styles.
p.s.
But if you want to have only one view/style copy , take this file from:
gk_league_news\html\com_k2\templates\default\item.php
and copy to
gk_publisher\html\com_k2\templates\default\item.php

First of all thank you for you`re fast answer, but still dont work. Another method ?
