XEvent Theme

Is anyone else having issues that once you install the theme it looks fine but once you go live, it doesnt look anything like the original theme appeared? I see that many downloads are happening with this theme everyday and I cannot figure out why everything would lay out fine except for the picture slider header at the very top of the page.
I havent included a link because I had to go back to an old theme as the new theme looks so bad. It actually looks like the page is blank until you scroll down and see the posts and the three column ads and so forth.
