How can I use a WHMCSthemes.com theme as my WP theme?

I had purchased a whmcsthemes.com theme so I could use their theme (I am essentially a virgin to wordpress) and what I would like to do is use the WHMCSthemes.com theme (https://www.whmcsthemes.com/premium-whmcs-templates-fast-hosting.php) as my Wordpress theme. Is this possible and how can I go about incorporating THEIR theme into my WP installation? I just purchased the one-month to give you guys out a try, you have quite a few nice plugins, including the WHMCS ones - thats what sold me.

Look forward to your reply.
