Technical Support Blender Theme

Hello, I bought the blender Theme and installed it. The installation was succesfull, but I can only see the standard Dashboard. If I open a site, I see a grey blank site. How can I change this?
I contacted the Author (ignitethemes) of the Theme already two times with the contact form, but I get no answer and Support is disabled for the Blender Theme, also comment tab is not possible.

The reason you couldn’t ask for support is because the item is not supported by author. If you need support from someone other than the author message me here, I’ll be help you with the theme.
