I have cancelled 3-Month-ESO-Plus in Steam (message was: game was removed), played the game as normal, next day added 1-Month-ESO-Plus in Steam.
Now Steam downloaded 30% of the game again. When this was finished, I started the launcher. It verified the files and after 10% starteted to download the whole game again. But the whole game is completely on my harddisk!
This takes me about 5 days before it is downloaded again. What can I do??
