Windows 7: windows 7 firewall & counter strike source

Hey,



The first time I started counter strike source on windows 7 i got a message saying "windows firewall has blocked some features of this program". It also asked me if hl2.exe could communicate with private networks and public networks, what does this mean?

I am currently running windows 7 RTM 64 bit. I know that steam is a 32 bit application but I've read that counter strike source is a 64 bit application. However when i look at the hl2.exe process it says "hl2.exe *32", which means that counter strike source is running as a 32 bit application. Can somebody explain why this is?

does anybody have an answer?

Try to allow it to communicate through firewall...
