Can I play my Sims 2 expansion pack if its in another language?

I have The Sims 2. So far I have bought The Sims 2 Seasons, The Sims 2 Pets and The Sims 2 Nightlife. Recently I have bought The Sims 2 Bon Voyage and The Sims 2 Freetime. There's just one problem; I accidentally got Sims 2 Freetime in a language that isn't English! The back of the case and the instructions are in something I can't read. I haven't installed either of the new expnasion packs onto my computer yet; will I be able to play?!
