Sorry about the triple post... but we have progress!!!
I remembered back when the creator's update first dropped, I had an issue with RTSS and sims 3 crashing on load. So I closed out my RTSS and I am finally able to load the game.
So, I found the cause of the crash, I'm just not sure how to fix it. I need that RTSS to run my game. It's the only thing to keep fps capped (other than bandicam).
Thank you everyone for your help! :) I'm sure I got it from here, I just got to figure out how to get RTSS to play nice with Sims 3.
