Error: Could not initialize internet connection.

[Grachmark]

Hello everyone,

I post this Thread because I really want to play but the problem is that, after have perfectly follow the instructions on this website, I just can't launch the client installation.
When I launch launcher.exe file, i get this message: "Error: Could not initialize internet connection.", and it's unnecessary to say that I am, of course, connected to the internet.
I precise that I live in France, I run the program on Seven with SP3 in Properties/Compatibility and... Please help me! I am really fan and I really want to find the problem to solve it.

Thanks.
