I already downloaded and installed the theme via "only download wordpress file."
I am still getting this issue. I want a refund if iam told that i have to buy an installtion service. I refuse to pay further for something i could have solved with buying a mere wordpress theme off of wordpress. I just thought this theme was rather unique and awesome.

Did you read the documentation with the theme?

No WordPress theme (regardless of where it is purchased) looks like the demo when installed until you import either demo content or create your own.

This will be either via xml or via theme options but the documentation should cover the process or you can ask the author.
