Dungeon Architect

Hello I bought and downloaded Dungeon Architect [Unreal Engine 4] – Version 2.1.5 (Windows)
In the folder there is a quick start guide that redirects to the website and from there I downloaded the Quick Start Content pack for Dungeon Architect version 2.x. and installed it to my project.
The problem is that when I open a map from that download the themes are not set on dungeon1 component. Also when I open the theme files they are empty.
Can you tell me whats wrong ?
