In the medieval 2 launcher, the settings button allows me to set proxy settings. The launcher has been having problems recently, telling me I can't connect to update server and that I should check proxy settings.

I have no idea how these settings work, but is it possible to adjust them... or just fill in these blanks: proxy address, port, username, password, and make things work?

Yeah I'm a technonoob, but if this doesn't work the launcher just doesn't work at all I guess.
