Campaign Map editor for RTW 1.3

Hi!
I'm wondering where I can find a campaign map editor for RTW 1.3.
I've looked just about everywhere, and I can't seem to get a hold of 3DSMAX.
Forgive me if this topic has already been posted, as I am a newbie to the guild
(although I've been with RTR for over a year)

thanks
