Theme error in IE! Help?!?

Hi! My theme works just fine with firefox, chrome etc... But with IE the header is all messed up! I've tried almost everything and nothing...
I have this section in css:

/*/////////////////////////////////////////

///////////////// HEADER  /////////////////

/////////////////////////////////////////*/



#header h1,

#header h1 a{

	width:990px;

	height:139px;

	display:block;

	text-indent:-900em;

	margin:0px;

	padding:0px;

	}



#header h1 a{

	background-image:url(pix/logo.png);

	background-repeat:no-repeat;

	}



#header h1 a:link,

#header h1 a:visited				{background-position:0px 0px;}

#header h1 a:hover					{background-position:0px 0px;}	



#header .floatR						{padding:25px 0 0 0;}

#header .floatR ul					{list-style:none; text-align:right; margin:0}

#header .floatR ul li 				{display:inline;}

#header .floatR ul li a 			{padding:3px 10px; margin:0px 3px; font-weight:bold;}

#header .floatR ul li a:link,

#header .floatR ul li a:visited		{color:#FF6600;}

#header .floatR ul li a:hover		{color:#669900;}

Code (markup):
