Battlefield 3 Beta Template - HELP NEEDED

I downloaded a Battlefield 3 beta script (google "battlefield 3 script" ) and I want to little edit it for another game but when before that I checked if the template is working. I uploaded all files from that downloaded .rar archive but it's seem it doesn't work... when I upload all and refresh my site there is white background with one line of text+images won't display. I have hosting on hostgator . Sorry for my english and noobish but I'm new in it. I really want to get it work. When I try to open index etc. files from my desktop they work but when I upload it to hostgator they didn't... only white background. Any ideas what's wrong with it ? Maybe someone can help me get it work ?
