Destroyed the launcher

I have no idea what you guys did, but whatever it was... UNDO IT!! yesterday it all worked just fine, and since today (19/04/2017) Everytime i press launch, The screen just disapears and the games just shuts down! I already uninstalled Twice, rebooted my laptop, reinstalled, Tried upgrading it twice and the problem still continues . So it cant be a problem with my laptop but clearly with some joke you guys started to piss off players.

Any advice on how i can still run this buggy game?
