OK so I had the same problem with the launcher, so looks like people that has the game installed via STEAM are having this problem, their launcher gets stuck and it doesn't move on from that point forward. All you need to do is uninstall the game from STEAM and download the installer from the game's website, just login into your account and hit DOWNLOAD, after that just open the installer and you should be fine, the problem is with STEAM not the game.

Second problem is the crashed every 5mints or so. The best thing you can do is roll back your graphic drivers or delete them all and install them manually make sure that the driver is for your windows for example: (358.60 Windows10 x64bit) is good to this manually that way you can see for what windows the update compatible, I'm saying this because one of the latest updates for Nvidia GEFORCE GTX 760 graphic card(my current graphic card) wasn't compatible with Windows10 and it gets installed or it might have some problems while installing, it can crash during installation or it wont install at all, if it gets installed it will give you problems with your game making it crash several times, making it impossible to play. So I do recommend you roll back the graphic drivers.
I hope this has helped you.
