if u have the game on steam, verify the game files for it and maybe that will fix the problem

Buddy, i want to REDO the whole translation - make it better.
My game is working fine.
I just want to know how i can access the text files, and also what i need to edit them.

Hello!
 
I always wanted to fix the Polish version of COD:WAW cuz its not so good and also its missing some things.
So my question is... What do i actually need to access the text files? How can i edit them?
 
I hope somebody can explain it to me.
Regards.
 

Hello !
I have big issues with this modification, lets start at the point that i instaled everything correctly so the mod is launching but thats enough of success i guess. So every time i go into zombie mod the game stays in ''connecting'' mode, then i tried join maps via console but after loading the screen stays black and even map restart via command isn't working. I really don't know what to do, if someone can help me i will be glad as hell.

PS: I have original Polish retail Steam version with all DLC's with i buy separately.
