Game Freezing ( after installing mods )

I have few problem with mods. ( I use only mods compatible with BG2:EE )
If are mods instaled in English language, then is everything fine.


But if I make some changes in mods text files, for example, a translation into another language, game starts to freeze.
In the best case appears "Invalid: 119986" (or any other number)


What can I do ?
I want to translate a few mods for my community.
