Can't update the game, wants to re-install?!

[Chronos-22309]

I tried Anduin on the PTR today. After I was done, I wanted to switch back to Europe.

First, the Launcher wanted me to “install” the game. Which was odd, since it obviously already was. Then, after using the “locate files” dialogue, the button turned to “Update” again. But everytime I try, it only VERY HELPFULLY tells me that “something went wrong between our server and your client. Give it another shot.” Which obviously didn’t work, otherwise I wouldn’t be here

Suggestions?
