Pets expansion problem. [CLOSED]

I installed Sims 3 and most of the expansions. Everything works normally, except when I try to make pets, they are invisible. The expansion works and I have all pets options and everything, just the actual pets and pet-related furniture is invisible. 
I can adopt pets, but they won't appear anywhere. I cannot even buy pet furniture, because when I click on pet tab, nothing happens (it doesn't open a list with furniture like when you click on living room tab or something).

Does anyone else have the same problem?
I downloaded Pets (fixed) torrent from games4theworld piratebay site.
