Method 2: Cleaning Steam’s Cookies & Cache from 3rd-party browser

Several affected users have confirmed that they finally managed to get around the error by visiting Steam on a 3rd party browser and buying / downloading the game from there. Doing this will force the desktop client of Steam to download the game.
