So Ive downloaded Sims 2 and all the expansions but now I dont know what version of c

of crack do I need to be able to play the game??I mean I installed first Sims 2 then Pets, then University and then Nightlife(yes I know that the Open business expansion is missing) and after all that I download a no-Cd crack for SIms 2(the main game) and did all correctly but than the game didnt work!So I was wondering if anyone knew what version do you have to crack when you have multiple expansions in order to play the game.Thanks

nevermind
