aghhh! I deleted the search box from header and lost my top bar nav links

Hi,
I wanted to remove the search box from the header in the Creativix theme. I followed advice on a thread on the forum to remove the code below but it removed my page links too! The code below wasn’t identical to the code I deleted so I can’t paste it back in! Where will I find the original header.php code for the Creativix theme because it was from the parent theme that I deleted it, now I can’t get it back!! Help!!!

<div id=”search2″>
<form method=”get” id=”searchform2″ action=”<?php bloginfo(‘home’); ?>/”>
<div><input class=”searchinput” type=”text” onfocus=”doClear(this)” value=”<?php _e(‘Search’); ?>” name=”s” id=”s” />
<input type=”submit” id=”searchsubmit2″ class=”search_button” value=”Search” />
</div>
</form>
</div>
