since the new update, it seems that hb crashes on those who have windows 8 just after a few minutes, I have the same problem, but also a solution. If you continues to open new hb after it have crashed so in the end so it will not crash. It usually works after that started hb 5-7 times after the crash
If you're having the crash issue with the newest beta (#623), I still need to find someone to figure out what the problem is. If you're up for it, PM me TeamViewer or Skype details please.
