Remove 2nd menu section for BuddyPress signup/login in Product Theme

Please advise... I'm using the Product Theme... I am not using it with BuddyPress so I have no need for the members login area. How do I Remove the Admin Login Button on the Homepage? What file do I edit to delete this section? I can see in Firebug that the code is:

<div id="signup-section">

<p class="signup"> </p>
<div class="clear"></div>
</div>

thanks!
