No editor for steam?

[Cribban]

So I bought MoW over steam (love the game!) and I've been playing for awhile now. So yesterday I feelt like trying out the editor and make a map, here's where I ran into something strange.... The editor is nowhere to be found? I read somewhere that it ships with the game, is that right? Or is it that steam users get left out?

Sorry if this has been posted elsewere
