Could you please email your query to hello@multipurposethemes.com I am sure there is some minor error. As you are part of Themeforest you know that all items are checked before uploading.

Just to confirm that you are not using this as a WordPress theme. It’s an HTML template and not a WordPress.

I am an idiot. It installs just fine if you know what the hell you are doing. I apologize.
