In your menu.css file, find this block of css:
ul#cssmw1 ul.level-2 > li > a, ul#cssmw1 ul.level-2 > li > a:link {
You would want to change the margin: 0; to this:
margin:0 0 0 45px;
So the end result is:
ul#cssmw1 ul.level-2 > li > a, ul#cssmw1 ul.level-2 > li > a:link {
background-color:#517595;
background-image:none;
border-bottom:1px solid #FFFFFF;
border-right:1px solid #FFFFFF;
color:#FFFFFF;
display:block;
font-family:"Trebuchet MS",Helvetica,sans-serif;
font-size:12px;
font-style:normal;
font-weight:bold;
margin:0 0 0 45px;
outline-style:none;
padding:5px 10px;
text-decoration:none;
text-transform:none;
width:auto;
}
