deleted database - restoring it

Hi, i have this website [login to view URL] klip .dk - it is a video website like [login to view URL] - it is originally installed from a script but unfortunately the database was deleted a few days ago. The original database has been installed again - but there has been some programming on the site since it originally was installed and i think that might cause that the site isn't working as it did before the database was deleted.. like you can't view a video.. if anyone can help i will appreciate it alot.. thanks nicolai
