Hello, i've some problems with my SourceForts. Im new in this game and i've just installed it, it shows in " My Games " i can play it but not in the internet beucase when i click in Internet, there are no Ips, i click in the Favorites i add Ip's and even this way doesn't works. I've HL2 installed, i've SOURCE SDK Base installed too, i've the game CSS and im trying to playing it in the account of CSS and HL2 as well. So my problem is that i cant play in the internet because no ip's found inside the game and when i try out of the game in the Servers List of the Steam it works but says: You have not the 3rd party installed. So please help me to solve this issue.

Thank you,
nonamez.

I've had the ingame issue a lot before. I can't actually say how to fix it, but did you try connecting through console? (ie. connect IP.IP.IP.IP:PORT) When I had the issue, that would sometimes work and after I connected to one server my master list would work too.

Also have you done all the basic network checks (firewall, router ports, etc)?
