Launcher Has "Stopped Working"

[BannanaWaffles]

Hey,
I just installed the base Sims 3 game, no expansions or stuff packs yet.
When I went to run the launcher, it takes a second, then comes up with the standard windows "Has Stopped Working" error, no other details.
If I try to run the executable directly, it starts loading and just as the bar hits the end, it just.... closes! No error message, or anything, the game just closes without any hint to why it would have closed.

I am running Windows 7, for reference.
