Activation template - corrupted files

I have 2 problems
First: After downloading the template and install it on the Wordpress I can not activate the template knowing that I write all the required correctly as shown in the attached picture
Second: The file is incomplete or damaged and I tried very much to talk or follow up with the author but without any reason
I spent my money without any value
Is there a solution to my problems?
I’m sorry but I really got tricked into this site
