No Thank You : unable to play full screen

Everytime I tried to select full screen, something wrong happened. It's either

1. The interface became a full black screen with a small pixelated screen of the game

2. The game froze and exited by itself...

Idk whether something is wrong when I extracted the file but there is supposed to be a 'ev2.ypf' which is missing from my folder (???) I am not sure if it's related...

I would rather not download the whole thing again (which is around 3GB). Please help T A T
