I have the Polish retail version of the game and I can't find any way of changing the menu or in-game overlay text to english. It's all in polish. Can someone please help?

I had to do this for AC2 aswell, except it took me a couple of days searching the internet for the english version of the DataPc.forge file.

I got this game over a week ago and in the beginning the game kept crashing, running slow or something else, now that the patch came out and I've finally gotten it to work, I can't find any way to change the text to english.

It is really annoying playing any game like this. I've been living in Poland for 4 years now and most games have an option to install the game in english or in polish. Why doesn't ubisoft do that?
