Your logo IMAGE is 120 pixels deep, but your stylesheet says:

Code:
#logoWrapper{

	background-image: url(../images/header_bg.jpg);

	background-repeat: repeat-x;

	background-color: #ffffff;

	height:75px;
Your logowrapper is asking for just 75 pixels !

Change to:
Code:
#logoWrapper{

	background-image: url(../images/header_bg.jpg);

	background-repeat: repeat-x;

	background-color: #ffffff;

	height:120px;
