[W / v.09722 ] You can't run the game in 3 different languages.

I had a problem with the Polish language. I checked all the others. Bugged are: Polish, Slovak, Japanese.
The game takes the language of the OS. What new buyers  from the countries listed above can see  - Black screen.
I think this is emergency fix .
