How to get the WHMCS interface to show up on WordPress

How to get the WHMCS interface to show up on WordPress site? I created a page which contains the [wcp_content] shortcode and I used it as "Default Content Page:" in WHMCS Integration. But still WHMCS interface doesn't show up. WHMCS directory is not in the root of "2014" but in the root of the website. I wanted later to copy the content of "2014" directory into the root of website when everything functions ok. Is it a problem?
