From Blizzard Customer Service:
There have been multiple reports of black screen issues being related to the use of a Quick Cam webcam.
In some cases exiting out of the software has resolved the issue but others have reported a need to uninstall the software for the camera in order to resolve the problem.
There are also reports where some security programs like Comodo firewall can cause the game to start and stay on a black screen.
