Sims 3 (Error loading after installing High end loft stuff)

This has happened about 3-4 times...I download Sims 3 and Katy perry sweet treats without any problems and install the store items that I like...then I want to add the expansion packs to the game and follow the instructions, I open the game and it says unable to load game or that some modifications that I've installed doesn't match the game and that it will be laggy/buggy... I don't know what's the problem, I add the crack to program files(x86)-electronic arts-sims 3- game-bin and put to replace there but after I do that, it all goes downhill.

I've had to uninstall this game so many times , it's annoying and I really want to play all expansion packs..specially with seasons coming and supernatural...please help me.

Hi, can you please check what version of the game you are running. This is found here.

If your version does not match download and update to the latest from here.Update 1.36
If it does skip downloading it.

Once your game is all up to date download the Latest Ultimate Fix from there and copy the #crack to your bin folder inside *\The Sims 3\Game\Bin

Now your game should be fully functioning.

If it still gives you a error about modified stuff its probably because you have an outdated mod or CC
Good Luck.

Thank you:] I'll re-install everything again and retry...just a question how do i know if it's an outdated mod and what's a cc?
