Totally lost 30 seconds in

Well, hello. I just bought this theme, and 30 seconds into the installation, I am thoroughly confused. I am hoping someone can help me.

I am trying to follow the installation instructions in this video, but 30 seconds in, it lost me.

My admin > shopperpress > general setup doesn’t look anything like the one in the vid.

I would like to use this shop template.

Actually, I was very disappointed that all the templates didn’t show in the drop down menu like in the video. I wanted to have them all and try them out one by one and then choose the best one after.

How to install this?

Please use step by step and simple instructions as I am not a coder or software professional. I am simply an entrepreneur.

Thanks!
