Not sure if anybody knows or not, just bringing it up. There doesn't seem to be a map for Hickory Branch. I tried to re-install my game twice just to make sure it wasn't a faulty install, but no, it's still not there. It just displays a big black box with a cursor or two in it.
If you are talking about a townmap, then follow Allyx's post. If you are talking about a game map your characters walk on, then your install is faulty.
