Having a similar problem, except on Windows 7 64 bit. Changing software render to true does nothing, and from what I can tell, the debug log is empty. It simply hangs and pops up with a message that it’s stopped working. Tested with both the stable and one of the experimental builds. Can still run 0.A tiles just fine, as well as 0.B Curses, but 0.B tiles simply doesn’t work.
