This is a small update, but hopefully it will help make it easier for new players to get into the game.
Some people have been having issues with setting the screen size correctly. I found out that the configuration file, which was supposed to be in the "C:/Program Data/Paradox Vector" folder, was actually residing in the game's root folder. This caused a problem when setting the screen size initially. That extra file has been removed, so hopefully this will not cause problems in the future.
Also, I set the default screen type to full-screen, and the window size to match the native resolution of the player's monitor.
I hope these simple changes may help new players get into the game right away, without having to wrestle with monitor settings.
Let me know if it's working good for you or not.
