Can't figure out why my header disappeared

Hi,

I’m using Thesis 1.8, Network News Skin.

My site is: https://www.alpineathena.com

My header has disappeared and I can’t figure out why. When I go to the custom css the link is still there.

.custom #header #logo a {
display:block;
width:384px;
height:100px;
/* insert the file path to your logo below */
background:url(https://box744.bluehost.com:2083/viewer/home1%2falpinea1%2fpublic_html%2fwp-content%2fuploads%2f2011%2f03/logo.jpg) center no-repeat;
color:#000000;

I’ve gone thorough all the colors to see if maybe it accidentally became white, but I can’t figure out if it had.

Any suggestions?

Thanks!
