Sims 3 - Master suite stuff

Okay, so I've tried looking for a solution to my problem and it seems like I haven't found anything. I'm sorry if someone else posted something like this and I overlooked it.

So I bought and installed: Sims 3, Ambitions, World Adventures, and Pets.
I installed theses from you: Fast lane stuff, Master suite stuff, and town life stuff.

I followed the directions for how to setup The Sims 3 correctly. I updated the game with your update and put the files where they needed to be. I loaded up the launcher, and it went into full screen mode. Played The Sims 3 preview. It looked like it loads like normally, except when the bar of the loading screen gets to the end, it freezes, and the music stops. [so I know it froze]. I've been sitting her for about 20 minutes trying to see if it unfreezes. Ultimately I had to force shut down on my computer. (It wouldn't let me escape full screen mode).

What did I do wrong? D: Is there anyway to fix this?

Sometimes you can overlook things.
Make sure to read it CORRECTLY and thoroughly.
This usually fixes problems such as this.

I know it sucks repeating things over and over.
But going back through that guide helped me with a lot, even when I thought I did everything perfectly.
