The Sims 4 Mac Flickering/Blinking/Missing/Glitched Graphics on Wineskin

Hey,

I have successfully downloaded The Sims 4 on Wineskin. But, the graphics are completely messed up. A lot of the buttons are missing. They're functional (as in I can click them) but they are transparent/their graphics don't work.

As I am writing this, I tried launching TS4 again and found that it freezes at the first loading screen. I can't go passed that.

Any idea what I can do?

Thanks.

--I also don't have anything from any of the EPs. I was under the impression that the G4TW download included those?
