At first I'd like to thank all of you for your help.

I'd also like to say sorry about writing about Divine Divinity on the Beyond Divinity forum. Obviously my fault, but it was a bit late so forgive me. I think my thread can be moved to the proper category and you may also delete it if you wish 'cause I have nothing against it in fact.

Now about my polish version of the game.
First remark: I've bought an original copy of the game
Second remark: maybe I was not precise enough - in fact only dialogues, names of different items, sign texts and, you know, all the writing has been translated into Polish but for example voices stayed English. So I don't know, maybe it's not a fully Polish version (as I've said) and so the patch could be installed...

Once again thank you very much and of course: have fun!
