Lightbox position

Hi.

My Lightbox is floating left. although I do not have anything telling it to do so. I would like it to be exactly above the page below .. but uh .. I get it all wrong. custom CSS:

body .modula-fancybox-container {
text-align: center !important;
max-width: 1024px !important;
max-height: 950px !important;
top: 250px;
margin: auto !important;
z-index: 999999998;
}

any idea ?

The page I need help with: [log in to see the link]
