Some server locations are serving corrupted files, and that is why many of us can't update the game (most of the south american players, and some regions in the US).
Solution (english):
1 - Close the ESO launcher
2 - Go to C:\Elder Scrolls Online\The Elder Scrolls Online\depot\patchdata.depot and delete all the files that are listed as "partial download" (the path may be diferent, it depends on where you installed the game)
3 - Install hotspotshield (other VPN softwares may work too). www.hotspotshield.com
4 - Open hotspotshield and connect to the USA location (if you are connected correctly, the icon on your task bar should be green)
5 - Open the ESO launcher and resume the download.

Thanks to
@OsielGam3r for posting the hint of using a VPN service.
