Counterstrike login problems

[Ferranti]

I ve got the original half-life game (german, own key) the german update to 1.1.0.8 and the counterstrike mod 1.3.
but when i tried to login to servers it always says "failed valid to the won.net" (or something like that)
can anyone help me with this problem?

thanks
