The update you got is the correct update, you will have the same version if you downloaded the full setup file. The EU ballot relates to an agreement that Microsoft reached with the European Union so that Microsoft would comply with EU anti-trust laws. Microsoft historically had a dominance in the browser market as Windows has IE pre-installed. The agreement led to Microsoft creating a a "browser ballot" system which would see its users presented with a page advertising other browsers. I believe Mozilla use the EU ballot downloads as a method of tracking how many additional installs occurred as a result of the agreement.
