This problem happens 2 my CS:CZ and my CS 1.6. When I click Find Servers in the main menu and the box telling me all the servers lists them, that works fine but the problem is that when I add a fave server it does not list in in my Favourites and it also doesn't list my History plus I cannot join my friends game when I click on "click to join your friends game" in my friends chat box. How do I fix this problem?

I also have problems with my favorites and history, My favorites delete themselves, and my history just doesn't work. No idea how to fix.

Favorites are messed up basically disable they last up to 30mins and go down. Unless you go to your Favorites File in your CS folder and move it to someplace I forgot where and it keeps your favorites forever, thats how i did it.
