When i try to join a game, i connect, adn when everyhting s loading, on the part where it says Precaching files or whatever, it stays there, and then exits, saying "timed out" but i know i haven't timed out, whats the problem?

that means the connection to the server timed out.

That can mean many things:

-The server sucks
-The server crashed
-Its a problem with your ISP
-A firewall is blocking access

i can connect to other games, but its just NS, i dont know whats wrong? i tried many different severs, and its all the same

can you connect to cs, dod, other servers?

yes, he said he can. Try to reinstall NS, if that doesnt work, redownload the beta 1 from a different mirror.
