Just a warning to anyone who experiences a CTD, clicking on the Reopen button may cause a CTD loop in which you will never be able to launch Diablo 3 until you reboot.

Clicking cancel and launching Diablo 3 will not solve this problem as the problem will not resolve itself until you reboot your computer.

If you experience a CTD Loop after crashing while in game, reboot your computer and this may solve the problem.
