WHMCS integration - wcp_menu does not show top menu

1.
When I use wcp_menu, it shows blank bar on the header.
Please see the header of my site.
I have a very new installation of WHMCS. ON client area of it, I can see the top menu, but it does not appear through this plugin.

2.
Second question: Using your plugin, Can I show a shopping cart on the top like http://demo.whmcsconnect.com/wordpress/emily/

Thanks
