Hi Christie,
An error message you received seems to be an issue related to the inconsistency in the system files or driver update. For us to resolve this concern, we suggest that you follow the steps below:
Step 1: Update graphic driver.
- Click on start button and go to control panel on the right column.
- Change the view by (from windows explorer) to large icons or small icons.
- Double Click on Device Manager.
- Expand Display Adapter, double click on the available entry.
- Click the tab Driver, click Update Driver.
Note: I also suggest you to update the display card driver from the computer manufacturer website as well.
Step 2: Clean boot.
It will start Windows by using a minimal set of drivers and start up programs. It will also eliminate software conflicts that could occur when you install a program, an update, or when you run a program in Windows. Please see this link for the steps.
Note: After troubleshooting, refer to this section "How to reset the computer to start normally after clean boot troubleshooting"
If issue persists, try uninstalling and reinstalling the game for the changes to take effect. Also, make sure to confirm with the SIMS 4 support if they have released any patches for this game.
Let us know how it goes after performing the aforementioned solutions. We'd be glad to further assist you.
