So i just installed Sims 3 Late Night. I was very excited to play it and couldn't wait any longer, but heart sinks as i see this "Unknown Error Occurred". I have four other expansions (Pets, Generations, Showtime and Seasons) and one stuff pack (High End Loft). I've studied on this "unknown error" for days now and nothing has happened. So I beg anyone for advice to fix this!
(I'm using a MAC by the way)
Thank you!

I also tried deleting my expansions and my custom content… didn't work….now i have no custom content…….. :evil: :evil: :evil: :evil:
I tried a lot of tricks from other forums and nothing would work but i figured out a rather lengthy solution that worked for me perfectly. This will involve re-installing the game but will mostly ensure that you will not lose saved content (I didn't lose anything). This was what I did on my Mac that runs OSX.
Here are the steps:
Stage 1: Backup the files
1. Go to Finder>Applications and drag and drop the Sims 3 application to an external HD.
2. Go to Documents>Electronic Arts. Save the Sims 3 folder to an external HD.
3. Now delete the Sims 3 application from your applications folder
4. Also delete the Electronic Arts from the Documents folder
5. Empty your trash of both the above files
Stage 2: Remove all traces of previous installation
1. Next, select Finder and on the top menu bar click on the "Go" drop down menu. As it appears press and hold the "alt" key and (like magic :P) the Library icon appears.
2. Open Library>Preferences. From this folder, delete the Sims 3 Preferences and all .com files (these appear as files with no icon images) that have the names "transgaming".
Stage 3: Reinstalling
1. Drag and drop the Sims 3 application from the external hd back to the applications folder (this could take a while if you have loads of extensions). Wait until it gets copied completely before the next step.
2. Go to Documents>Electronic Arts and delete the Sims 3 folder you see there and empty it from the trash
3. Now copy the Sims 3 folder from your external hd to the Electronic Arts folder.
Phew. Writing this was exhausting. But it worked for me! So all the best to all frustrated Mac Sims 3 gamers :)
