I heard about natural selection so i started looking for sites to dl it, I finally got NS 3.0 from the sticky, but whenever i try to join a server it says something about maps not the same or something. I dled the beta3 patch, does anyone know what i need for ns to work right?

You need NS beta 5, its a full install.

That install in the topic is really outdated, its about uh..4 months old?
You can get the correct version here
