The Sims 3 verify ownership

I've searched through the forum and the internet and can't find anything that will help me !
I'm in the process of trying to reinstall the sims 3.
I followed the instructions exactly as they said and I applied the ultimate fix but when i had sims 3 with expansion the launcher wouldn't start and when i tried to play without using the launcher an error popped up. something like this "initialization failed 0x0175dcbb". then i unistalled all the expansions and just had the base and then the launcher worked but before i could play it kept asking me to verify my registation code and i used keygen a hundred times until it wouldn't allow me to try anymore... so i'm going to uninstall and try again but some assistance would be nice.. I have a store bought version of it but its at home. on my old computer i had all my expansions from you guys and never had this problem before or one that i couldn't fix on my own. ppleeassee help !

Hello there,

No need to reinstall aything!
You either forgot to copy the cracked .exe file to the game's installation folder, or copied it to the wrong folder.
Please do as follows to fix your problem:

Open the "# Crack" folder in the .rar file you downloaded and then copy + paste (or drag & drop) the "TS3.exe" file in there to exactly: C:\Program Files (x86)\Electronic Arts\The Sims 3\Game\Bin  (Default installation location)  and REPLACE it by the existing one.
The game should work fine now, good luck!

Oh :/ I already did but it's working now so I must've missed something !
now my only problem is with my computer... it keeps telling me its low on memory when I have plenty of RAM.
