Luckily, I knew what the problem was. I had forgotten to add Showtime and Supernatural's .exe files to my DEP (Data Execution Prevention). So, I added them to my DEP and rebooted my computer. It worked! Yay!
If this is happening to you, with any expansion or even the base game then DEP may be your solution. A helpful tutorial for Windows 7 users can be found here by games4theworld. I have Windows Vista, and I will show you how to fix this crashing problem with DEP (if that is the cause) with pictures and text - isn't this exciting!
On to the tutorial...

Have you ever started up your beloved Sims 3 game to have it crash right in front of your very eyes? Sometimes it crashes on the title screen, other times while you're playing the game (which is extremely annoying!).
Do you see this pop up message?

Me thinks it's time to fix your DEP settings!
