Upon launching the ESO client it auto updated the full 20GB or so of the client.
In the game options menu click "cancel" then click "repair" that appears after.
I went from 10% download to 90% repair with doing this within the time frame of writing this.
Edit: Pausing the download is different that canceling the download.
