what does it mean when it says
Client_Auth_blablashit like that... i dont remember exactly what it says
"client unknown to auth" is what you are after? What it means is the master server can't, for some reason, authenticate your cd_key.
If your copy of RTCW crashes in the middle of a game and you then restart and try to join a different server the master server may not yet have released your CD key for use, in other words you may still be in zombie time on the old server. Once it times out for zombie time the master server will release your CD key and you can then join a game. There are other reasons why this happens - network problems between you and the master server - somebody has used a keygen program and produced a key identical to yours etc.
Hope this helps with whatever is the prob.
