I'm having various issues with it as well. Win7 64bit. I can make the "terrain" but if I save and reload the file, all I get is an emptiness. If I load the provided tutorial_1 files and such I actually see the right thing. Then when I close down it crashes. So the binary isn't happy on Win7, from reading posts it seems like WinXP is what it was originally developed for.
Wanted to add this version 7.4:

seems to be working better so far.
