[HoI3] fullscreen problem

hi everybody

ive been playing for over a year, until now i never had a problem, but yesterday when i tryed to start the game it didnt start at fullscreen it launched the game in a window
ive been looking for a fix cause i can play that way it doesnt show me the bottom of the screen im becoming mad lol
anyway anyone got a fix to this?

Hello ofteno,

U hate to open the settin folder:

gui=
{
language=l_german
}
graphics=
{
size=
{
x=1920
y=1080
}

refreshRate=60
fullScreen=yes
shadows=no
shadowSize=1024
multi_sampling=8
anisotropic_filtering=0
gamma=50.000000

Find the line "fullScreen" and write "yes"
