//The Sims 3 decrapifying problem// HELP! [CLOSED]

So I downloaded my The Sims 3 game and some ep (Island Paradise, University Life, Ambitions, Seasons, Movie stuff, Katy Perry Sweat Treats) from Games4TheWorld.org and it all works perfectly! I also installed some cc from sites like mod the sims etc. And recently I tried the The Sims 3 exchange "hack" to download cc without registration and it worked, but when i tried to install it it said "Installation failed please make sure your game has the latest software updates" I checked and my game IS up to date. So I saw on the internet that I needed to decrapify the files using the decrapify area, and i did everything step by step 3 times, it still didn't work. I also installed CC Magic but I have no idea how to use it and i think it wont help. Can you please help me. And sorry my english is bad cause its not my first langunge.
