i rebooted conputer but the key still doesn't work.

i don't know why.

i also used this

to write korean, 

and it doesn't work,too.

but,according to this, i can guess it is not keyboard-problem.

i think i did wrong set-up in the mornig without my aware.

it is too unconfortable.

i am a student so i have a index to write in korean due to this weekend.

i don't know grammar or speeling is wrong. 

my mental is breaking down

it is my brother's who is in army

if it will have not been fixed he will kill me.

so sad 

help me
