Last night I tried to download the 1.19 patch, and I got the above error when it came to actually extracting it. So I just uninstalled the game and redownloaded it, hoping this will fix the error, but I got exactly the same issue. I've just checked the temporary folder, and I see a 1.91Gb elemental1.19[b].123.impulse file there, so its downloaded fine, but Impulse doesn't seem to be able to extract it?
