I found my older brothers x2 the threat game, the voice language is in english, but the text is polish. I can't read it to know how to change it or if you can change it, cause my brother is famous for buying stuff in different languages like movies and such, so can i change it? If yes how?

i bought Call of duty 5 world at war in Poland, at a normal store, its a registered full, good , NOT copied game. how do i change the language to english, like is there a patch or something

My daughter is getting married and somehow I got the task of planning her surprise wedding shower. Since almost every woman at the shower will be Polish and our family is not, I want to play one shower game with written instructions in English and in Polish. My idea is to have a large bowl of candy hearts on a table and the guests have to guess how many candies are in the bowl in order to win a gift basket. Therefore, I need to know which of the following sentences is correct. I got these versions from the internet (free English to Polish translations). I have no idea which is the correct one to use for the two signs that I am making. I'd hate to embarrass myself and my daughter by writing the wrong words. Please help!

ARE THESE CORRECT?
Guess how many candies are in this bowl for a prize.
Zgadnij, jak wiele cukierkow sa w tym miska dla nagrode.

I appreciate your help but I really need to hear from someone who speaks Polish fluently. I've tried the free online English to Polish translators (such as http://www.poltran.com/pl.php4) and they are not grammatically correct, so I've been told).
Kelly, that suggestion would be really appreciated. The shower is a couple months away so I've got time to prepare.

Somehow the game is in Polish and can't find out how to switch over to English.

Thanks
