sims 3 base download.[SOLVED]

so i uninstalled my sims 3 base game from another torrent site so that i could download games4theworld base game so that following
guides and all that would be easier i thought. i mounted both of the disks in the file but when i am installing it the little box comes up and says that the setup needs the disk that contains the file GameData/Shared/Packages/FullBuild.1.Package. ..but when i go to the sims 3 startdisk i mounted, it won't let me open the package file so that i can get to the fullbuild.1. 
i know its there because when i went to my libraries to look for it and make sure i saw it, but the setup says it couldn't find a specific disk or path.

im not sure if i explained this well enough, so if it needs more clarification let me know i can screenshot it...i just want to know what i have to do in order to get to this file

Are you sure you launched the correct disk first?

 I think so, if it's the one that says SIMS3. Can I just crack one that I bought on Origin? I didn't know if it would mess it up if I cracked it... because the setup won't let me open the fullbuild package which is weird.

You can simply install the base game you downloaded from Origin and follow the instructions mentioned here. Keep in mind that the correct directory in step 4 should be: C:\Program Files(x86)\Origin Games\The Sims 3\Game\Bin instead of C:\Program Files(x86)\Electronic Arts\The Sims 3\Game\Bin.

 thanks so much i did it and its back and working fine (: 
take care
