Forum setup help!

I recently got a forum (or bulletin board) script from www.webscriptworld.com and did everything the readme file said word for word and uploaded it through ftp to my new page at www.f2s.com (www.clanlapd.f2s.com/forums/admin) When I go to see the page the readme said to, I get this:
Forbidden
You don't have permission to access /forums/admin on this server.


--------------------------------------------------------------------------------

Apache/1.3.19 Server at www.clanlapd.f2s.com Port 80

I did exactally as the readme said, what happened?

I'll send the readme file with this post so if anyone can help me out I'd appreciate it alot.
Here is how my directories look in my ftp program

|_> www.clanlapd.f2s.com
---|_> forums
----|_> forum.phtml
----|_> subscribe.phtml
----|_> unsub.phtml
-------|_> admin
--------|_> admin.phtml
--------|_> index.phtml

Just like the readme said. I can't view any of the directories or files through my browser. the read me said "Access the admin from "yourdomain.com/forums/admin/login.phtml"
So I went to www.clanlapd.f2s.com/forums/admin/login.phtml can someone pleaseeeeeeee help me im new at this and im frustrated!
