When you get an image with an error and a bunch of numbers- what do those numbers mean? He says that it’s super easy to fault Blizzard for everything that fails in the online game, but he cautions that maybe we ought to search for a different, user-generated cause.

Perhaps the graphics resolution settings are too high and your personal computer can’t handle it or perhaps it is your connection to the internet.
