[[403] Forbidden]

Hello, thanks for my friend invite me to this forum.
Anyway...

I found out the problem when I tried to run Counter-Strike: Source. It's show up with Loading on below right. Just after loading, disappear and back to desktop. Even I noticed Counter-Strike: Source - 100% - Ready to play.

My computer specs:
2.8GHz, P4 Extreme
2GB of RAM
Nvidia GeForce 7800 (78.01 - Already updated)
9.0c Dixc
Window XP SP2

Can anyone help me out to solve the problem?
