script killed my website

[محروم.كوم]

I insterted a script form a company we work with from their website, banner text.. inserted it into a box, allowed script tags but when i go to home page now, all is gone, except the one box that has banners and they are scattered all over the main page. I also cant seem to get into the control panel by typing the url nor the admin section.
