[Game will not update or let you start game]

I'm getting Lunch error message every time I log in and try to restart the game. Before that I get the message "Version check error". I'm not sure why it won't let the game update or why I can start the game.

[Game Download Link gives 502 Bad Gateway]

As mentioned above, you can't really download the game and doing so is difficult because the Link that is provided gives a "502 Bad Gateway" error every time. To tell you the truth, I'm not sure how I managed to download the game previously. And even after downloading the game, the luncher does not auto update itself when a new patch comes out.
