@eleanxr_dunkin That's strange that there wouldn't be a config file (you might not see the .log at the end)—it's in the same place as options. I've heard of a blank one before though.
At any rate, move your entire Sims 3 folder out of Documents\Electronic Arts and onto your desktop, and launch the game, which will create a new folder. Quit at the Main Menu (don't change anything), and look for the config file again. If it's not there, run the Super Patch (under Cumulative Base Game Super Patcher), trash the new Sims 3 folder that was created, and repeat.

If that doesn't help either, unplug your second monitor, restart your computer, and try again.
