Help with installing Late Night Expansion pack (Update issues?)

Hello. I have all of the Games4theworld Sims 3 downloads and I just bought Sims 3: Late Night from the online store. I downloaded it and I tried to install it but it told me I needed the latest update: Sims3_5.2.4.009001_from_5.0.44.008001. So I head to my launcher and it goes through the motions until I get to this error message: Update Error: Invalid file found. And then it says: The wizard was interrupted before TS3 could be completely patched. I don't know what to do. I'm very frustrated and feel like I just wasted money for nothing. How can I fix this problem?

Side note: I also downloaded some CC hair today. Could that be causing the problem?

Edit: I did try and delete all of the CC hair I got today, but it didn't make a difference =/. I guess I'm also trying to ask if this issue could be because I'm not using a legal copy of TS3.
