--- Comment #5 from Alzarath alzarath@archlinux.info --- This bug is primarily encountered when attempting to access maps or dependencies from Battle.net. After updating the game, I also have this problem when I try to start the editor. A simple workaround for that is to log into the StarCraft 2 game after an update. This only helps when starting the editor, though.
