try updating from within the game and not at boot. So load the game, when it askes to update say no, get to the game home page then go to I think its news or online something like that, it will then ask you to update again and it should work ok..
Try it again, although the bar resets, it actually keeps what it has downloaded, so eventually it will finish. In other words, if it fails at 50%, and you re-start the download, it will start the bar at 0 but will finish at 50 because it saves what youve downloaded.
This only works if you do it in the game menu though, when you click on the "news" option.
Its just a matter of keep re-trying and eventually it will do it.
