InfoScreen.SetInfo("s","S","s");

InfoScreen is a class. The compiler error is trying to say "which instance of InfoScreen should I call SetInfo() on"?

The answer is to name the otherwise anonymous Infoscreen instance you sent to StateManager.AddScreen:

void ShaneMenuEntrySelected(object sender, PlayerIndexEventArgs e)
{
InfoScreen screen = new InfoScreen();
screen.SetInfo("s","S","s");
StateManager.AddScreen(screen, e.PlayerIndex);
}


Note that I call SetInfo before the call to AddScreen, otherwise the AddScreen method might try to access the values before they are initialised.

Finally, have you considered moving the SetInfo() logic to a constructor for InfoScreen? That would eliminate a lot of this work, and is generally a safer and superior method to having manual initialisation functions.
