Hi DangerDahlia
Thanks for your patience while we've investigated into this issue- Have you moved the game's .exe, the game data folder, or the install folder to a new path or location after you installed it?
Please try the following steps:
- If you were able to create save data, be sure to back that up
- Uninstall The Sims 2 from the EA app
- Reinstall your game through the EA app
- Without making any changes to location, try running the game directly from your EA app library or from the desktop shortcut
If this doesn't clear up the error, your system may not meet the minimum specs required. In this case, you can contact the live support team here to get a refund processed.
