If you don't want to update your Counter Strike Source and still want to play the servers that n00bteam unlimited own. Then go to your Steam and right click your Counter Strike and click properties, go to the updates tab, and turn it to "Do not automatically update this game" then click close. After you have done that open Counter Strike Source and your ready to go.

If you already updated your Counter Strike Source. This is my opinion to fix your problem about getting the servers for n00bteam. Delete the Counter Strike Source off your steam and re download it. When it's finished downloading do the steps above. That is my opinion to get the servers working with mods again such as Role Play, Mini Games ,Dust, Zombie Mod.
