Can't go past the Launcher in Windows 10

[HawkFest]

Hello, as the title says I can't go past the Launcher screen. I've just acquired a new laptop, an HP Envy m6-aq105dx (hardware listed further down), downloaded and installed the game from the official page with High-Res dat files.

Then just to make sure, I've checked that there was an entry in McAfee LifeSafe Firewall, disabled UAC and started the launcher from its folder with administrator privilege.

I already have an account from 2 years back, so I logged in with that account and it recognized me (thankfully since I bought for around 100$ of stuff, mainly expansion packs). But whatever server I choose, when I select it and then click start, the Launcher closes and that's it, no game...

My Hardware:
- i7-7500U Intel CPU running @ 2904 MHz (advertised at 2.7 GHz)
- 16GB DDR4 RAM
- Intel HD Graphics 620 up to 8GB memory, driver v21.20.16.4639 (latest, with Windows 10 fully updated), resolution 1920x1080, shaders v5.1, OpenGL v4.4, OpenCL v2.1 Vulkan v1.0.0, DirectX v12.0

Any help would be greatly appreciated...
