Demo import problem,

Hello, I recently purchased the music play theme from you, in principle I thought I would be able to import the theme exactly like in the demo and work on it later (of course without songs), unfortunately what I imported is downright hideous, it has nothing of what I wanted to buy, I want to mention that this is the first time I’ve tried this type (online radio) and I would need extended support, or video tutorials, I didn’t find anything on YouTube. I’m eagerly awaiting an answer, thank you!
