[solved]pages not founds

Hi! i installed the script on my server (site hosted by hostonnet). No problem for installing it. But i can not access to the WATCH section, nor GROUPS setion. Footer links are not accessible ( About Us | Help | Advertise | Terms of Use | Privacy Policy ). I'm sure that all the files were uploaded at the install, and i tried the operation 4 time. Can someone help me, please? Thanks.

the .htaccess was missing....
