Ok, I managed to fix it =)The funny thing is, I was also trying to solve my other's game issue (it wouldnt save my progress) and the problem is in user account. So, I created another one which in NOT administrator and it worked for both games!! xD
Anuways, thank you for your effort, it took me 3 weeks to find the solution and you were trying to help me very hard. I apreciate it a lot!
Wish you goodluck(and raise in career), sir :3

C:\Users\USERACC\AppData\Local\DayZ
And AppData folder is hidden by default.

It is stored locally, I am sure of that. C:/...

That didnt help either.
The problem seems to me that Game neither open config file nor save changes.

Nothing was found by searching it. And yes, I do.

The question may sound dumb, but how do I download the file? ._.

1600x900

Seems like it isnt there.

I was kinda googleing the problem myself and downloaded default .cfg file but it didnt work.

Please, review^^
