@Da1franksta Is there any security software, or a cleaner app, or anything at all even remotely relevant that your affected computer has installed but your other one does not? If so, try disabling or uninstalling that software. And if the two computers use different internet connections, switch the affected system to the network the unaffected one is using.
If that doesn't help, try doing a clean uninstall and reinstall of both Sims 4 and the EA App. Start with Sims 4:
- Put aside your Sims 4 folder in Documents\Electronic Arts and rename it to something that doesn't include the words "Sims 4."
- Download Revo Uninstaller (the free version is fine) from here.
- Launch Revo, select Sims 4 from the list, and click Uninstall.
- Once the game is uninstalled, select "Moderate" under "scanning modes," and click Scan.
- Review the list, in case there's something you want to save; otherwise, click Select All, and then Delete.
- Close Revo, and restart your computer.
Uninstall the EA App with Revo as well. I don't have instructions for that at the moment, but the process should be straightforward. Restart again when you're done.
Install the EA App, then create a new folder into which you'll install Sims 4. The folder should be on the root level of the drive of your choice, for example C:\Games is fine, but not C:\Program Files\Games.
