Ok here is mine problem…
When I suddenly wanted 2 join a server I was getting the error VALID CDKEY IS NOT REACHING GUIDAUTH SERVER.
First time I had this but when visiting some forums and asking some ppl, I understood 2 delete mine etkey from mine etmain folder. I did that but ET didnt make a new etkey for me. So I started ET again and put the line: /pb_cdkeyreg in console I got replyed with PunkBuster Client: Cdkey Registration Request Sent to GuidAuth Master at 192.246.40.62:2760 (668296296) The last number is different from when I try it again. Now when I try 2 join a server I get Server disconnected by unknown reason. And yet still mine ET doesnt make a new key for me in mine folder.
This is what I also tryed:
-Installed ET again on other partition still didnt work didnt even get a etkey file in mine etmain folder when installing.
-Uninstall/Install ET
-Try some1 else his etkey file
-Tryed a other dns
I think this is all, If you can come up with smt which would get ET going back on track, I am really happy. It already costed me a war and I am in a clan and shit really sucky now it doesnt work.
plz help 

man I dunno what the problem was but now I can join the servers again, very weird idd,
