installation MUSIC STATE template

Hello, i have buy "MUSIC STATE ENTERTAINMENT JOOMLA TEMPLATE" and after installing this on my joomla administrator i see this:


Any element of the template does not load, of where can my problem please?

I downloaded the 3 necessary modules and install in addition since it does not work but the problem persists.

I use joomla 3.7.2, Do I need to install an older version of joomla?

Thank you for your help...

Hi

What You need is a quickstart version, which is a joomla on it's own, but with a content from our demo. Here You will find all the informations: https://www.gavick.com/documentation/jo ... stallation
