fullscreen unavaliable???

Hello im new player here since yesterday and I just downloaded the new patch *from the forum.* Im able to play but the game is automatically set in window mode. I just wanna play in fullscreen mode and whoever put out this download automatically set it at window. Is there some easy change i can do? Or perhaps maybe your admin in charge of this can make a game loader that opens in fullscreen like it should...? thanks in advance

 

i tried to find some readme in there wasnt sure which file i needed to read. Doing it myself wouldve been alot more cooler. But when you cant find the answer then i make the thread. Thanks AGAIN
