There's a much more convenient option.
This thing doesn't work for me either, and it crashes.
But if you close the editor, open the map with an archiver, and find Maps/Multiplayer_or_whatever/scripts. (in the editor, you need to have a map script created beforehand, an empty one works fine)
http://c2n.me/4d2H7mC, you'll get something like this.
Ideally, you open it in Sublime Text or Notepad++, and you also get syntax highlighting. And you don't need to download anything, except Notepad++, which is free and useful for many things besides Heroes. At least to open *.txt and *.xml files and have a normal view, instead of the eye-straining Windows Notepad, even if your text file has nothing to do with Heroes.
By the way, after editing the script and saving, the archiver will ask if you want to update the file in the archive (yes/no), so you can edit it on the fly. But with the map editor closed.
