@Quanir Hello there!
Thank you for reaching out to us!
Could you please try the following:
Open our launcher -> cogwheel -> change game directory -> create new folder on your desktop and choose that as the location
If that doesn't work, please try to get some free VPN and use that when trying to download the game. This should bypass any filters or network restrictions.
Also make sure you are always running the launcher as admin 🙂
