updated this morning and could not load game. Brings up black screen and cursor then nothing.
First look up this Blizzard Forums discussion page:
[BUG REPORT: BLACK SCREEN ON LAUNCH WITH CURSOR]
Second, a Blizzard tech will answer the post further down in the discussion. He will provide a link to the website to help you fix the problem.
Third, read this part after you have followed the steps at the website. It worked for me:
It says to change the program to the NVIDIA processor. Did not work for me when I changed it for just warcraft. But when i changed it for all of the programs that had “Blizzard” in it for example ( Blizzard Update client, Blizzard Browser). It worked.
i have same problem been trying to fix for days still no luck
