Can't start the game on HP Envy 17

Hi, I have had this game since beta stages and its always worked fine on my pc which has a dual core i3 2120 ( 3.30ghz ), a ATI R7-270x ( 2GB VRAM) and 8GB Gskill ram. I have played the game on my new HP envy 17 laptop with an Intel i7 processor, Nvidia GeForce 940m ( 2GB VRAM) and 12GB of RAM, before the 0.5.2 update. After the 0.5.2 and 0.5.2.1 update, I couldn't start the game. I launched it and all I saw was a black screen. It turns out that I had to update my dedicated GPU drivers...
