Hello,
To help a little, here is a tuto to show how and where to put the translation files.
It was made for a Mac version, but I think it's almost the same for windows.
Hope it will help although my english is not good enough.
I notice that a error can occur if you put directly the folder "resource" replacing "resources".
An "s" is missing and this can make trouble in the translation.
Knowing that, all should be ok ^^
The tutorial now:

If something's missing or wrong, just tell me and I'll correct it
