My Sim 3 game crashes back to the Desktop saying it has stopped.

Hello,

I am using a windows 7 (32 bits).I tried all your methods.I have also lately done a lot of research in different gaming forums and community pages i have almost tried all the steps guided.But still its crashing.Everytime I create a new Sim and start the game in a new town it crashes immediately back to the desktop.I have almost become helpless and hopeless trying new ways but i have received no such solutions so far which really solves the issue.

I almost added all the exe files in the DEP and tried that way also...i even tried adding the exe files of the different sub-folders under the folder written as packs, like TS3EP01, TS3EP02 etc.But it didn't work.I am using a pirated version of the game..and i downloaded all the towns and Expansions from torrents.I don't know whether it is because of that reason or not.But i don't think so.So if i can get a reply with any kind of solutions ASAP which might really help me playing my game as i've got sick and tired of seeing that same message saying "Sims 3 have stopped working" and the only option it gives is to close program.Please help me.Thanx.
