yes I did,your ini seems fine.
Anyway,I google it and found something:
Be sure that DNS-client is switched on in Windows.
Press Windows-R key combination. (This is the button with a windows logo on it)
Type in "%windir%\system32\services.msc" (without quotes).
Find a "DNS-client" service in the window at the right. Check it for being turned on and working.
Go to Start - Run (Windows XP) or Find programs and files (Windows Vista, Windows 7) - type in "cmd" (without quotes).
Type in appeared window "ipconfig /flushdns" (without quotes) and press Enter.
Reboot your PC and try to launch the game.
dunno what else.
if the above doesnt work also,try to close both consoles and re-open them.
