Unable to play any HL multiplayer games

[thefatkat]

Ok then, where to start. Basically Half-Life won't let me log on to any online servers for counter-strike, opposing force, the original game. Every time I try and log on it says my "cd key is not validated for Won.Net servers". I have no trouble playing single player games (my cd key seems to work for these fine). Can someone please help me ... as I want to get playing as soon as possible.

Many Thanks

Try sending an email to Won.net with your CD Key explaining that you are having problems playing online. They may be able to help you.
