Crack questions

Hey, i downloaded Generations, Late Night, Outdoor Living, High End Loft Stuff, Pets, Town Life Stuff, Ambitions and the Sims 3 basic one from your downloads. After that, i installed all of them and now my question is after the fix and all the threads in here, i kinda got confused.
After the installations, what do i crack first, and what do i need to crack at all? I opened the Fix and opened the Installation guide, but still don't get it? Do i just apply the TownLifeStuff&Pets&Generations crack or i need to apply the crack for each expansion?
Please explain it, because when it comes to this i have an IQ of a worm.

Hello,

The files in the Fix are not cracks, but the original files needed to update the game. The only crack - which has to be applied at the final step - is the one in the "# Crack" folder.
Just read through all the instructions and don't skip any step. (Only skip a step that requires you to copy the original files for an expansions to its installation folder, but you do not have that expansion installed)
