Game problems

i have the cd for the sims 3 base game and the sims 3 world adventures so installed them first then i installed the rest of the expansion packs through torrents from games4theworld.com i never installed any of the cracks just the patches and the ultimate fix. the game loads and every thing seems to be working fine but i get a lot of crashes. i downloaded 2 items from the game store but they dont show up. i ignored that and went on. i also installed a couple lots from thesimsresource.com and some of the lots are there but not all i ignored that and just picked one of the lots that were there. i downloaded all the expansion packs except the sims university life. i keep getting crashes i dont know what to do cause i am very new to all of this. it especially crashes when i go to build or buy mode. i just want to play the sims i got all the expansion packs because its more fun to play when everything is more life like rather then just playing with sims 3 and sims 3 world adventures. i don't want to buy the games so i downloaded them via torrents. is the torrents the problem? i see some people post that the game is working great for them via torrents. what should i do

(Our) torrents are no different from the regular game, in installation and play.

Try backing up and removing "Documents\Electronic Arts\The Sims 3" then let us know how the game runs.
