Re: Error Code 403:8717c2e9:20314deb

Could you please provide the following information

• Are you using mods/cc in your game ? Please remove them and test without them if you do.
• What platform are you playing on (PC, Mac, Playstation, XBox)

• Do you have any LastException files in Documents\Electronic Arts\The Sims 4 ?

  - Delete the ones you have
  - Trigger the error again
  - Check if new ones are created
  - If that is the case, please copy/paste the content here. You can open the file with any text editor.

  
  Deleting the file won't fix your issue. Posting the info is meant for troubleshooting. 

I do have mods, which have been updated to make sure they are the most recent version. I have tried without the mods but the same error appears. I play on my laptop. I know the error message has the name of one of my mods in but the error comes up even when I turn them off. This is it pasted in:

Please follow these steps to test  your game on vanilla game with no mods/cc

• Create a backup of your save game
• Move your mods folder to the desktop
• Delete the following files from your user folder.
  • localthumbcache
  • Any lastException Files
  • Any LastCrash files.
• Test on the backup of your save as you will loose all cc on the save and see if the same error occurs, then report back.

This is what came up this time:

Do you have issues with a particular save only or also on a new one ?

I've just tried a new one which wouldn't let me load the actual house to play and also wouldn't let me save. No new lastexception file was created though this time.

Have you tried renaming the entire user folder as well ? Usually if not even a new save works, that's the best way to go.

Try the following

- Close the game
- Rename Documents\Electronic Arts\The Sims 4 to Documents\Electronic Arts\The Sims 4_Old
- Repair the game
- Start the game. All your content will be gone now as the game created a new folder. All your saves/.. is still in the old folder so not to worry. 
- Start a new save game
- Check if you still have the error
- Report back with your results for further steps on how to get your stuff back.

Apologies for the delay. I've just tried it, and the game saved. Can I get my saves back somehow?

Hi ZephrynRose​ 

You can now start to copy back things from Documents\Electronic Arts\The Sims 4_Old to the new Documents\Electronic Arts\The Sims 4 folder that was created.

First only copy (I suggest to copy so you can go back in case anything goes wrong along the way) the content of the folder Saves (these are your save games). If you are prompted if want to overwrite a save, decide if you want to keep that testing save you just made or not. If not, just overwrite if, if you want to keep it, rename the save to a different number that isn't taken.

Test just your save game with nothing else added back. If that works, you can start copying back the rest. If not, check back.

You will need the following folders

- Tray (your households and lots you have saved to library)- Custom Music (if you added any)
- usersettings(.ini)
- Screenshots (if you've taken any)
- Videos (if you've taken any)
- ConfigOverride (if you made any although I recommend redoing those)
- Options(.ini) (although I recommend to just redo your settings in the game)

Now test again. If that still works, you can put back your mods. Put them back in groups and make sure they are still compatible with the game.

All other files are recreated and not needed.

Thank you. It seems to all be working now.

I forgot to test it in build mode. The second I did, it went back to being unable to save with the same error code.
