So this morning there seemed to be a minor update, which was failing to download for me
I tried relaunching the launcher a few times it always said there was an error in downloading the update.
I tried repairing the game 3-4 times, error too.
A friend of mine said his update worked after 3 attempts, so I retried a few times without any good result
So I uninstalled the game.
Now when I go on the download page ( http://worldofwarships.com/en/content/game/ ) and try to download it, I get an "Adress not found"
My friend can play but he also can't access the download page.
So i'm guessing it's a problem on your side Wargaming, but it's been 4h now and still no improvement...
