sims 3 problem, please help!

I dl the full back with all the expansions and decided only to use pets... i updated the patch, and i downloaded the same version crack to it. i have tried 4 different cracks now and nothing works,
with the original files i can get the game to start, (and it ofc says it needs the real cd)
but when i have adjust the cracks, the launcher opens but when i play the play button, the launcher goes away and nothing happens...
i have already tried to shortcut TS3EP05, when i push that, nothing happens either..
+ i have tried to reinstall and not use the latest patch and crack that goes to that version, nothing helps.... please help me i really want to play this game and i never had these problems before
