Sims 4: Error code 801

Hi, I have uploaded the file yesterday, please tell me if you cannot receive it.

Thank you again for your help.

Do you still have the broken save ?

Willing to share your save game ?

If so, please zip up this folder: documents\electronicarts\thesims4\saves and drop the file to this Mediafire-Link to upload.

Please make sure to name the zip file with your user name.

Hi, this time I deleted the origin and reinstall all the things again (because I can't log-in to origin when I try to use your method).

I started a new game and it works, I can join my Sims to go to the Scientist Career.

Then I tried to move my save back, the error code shown up again; I load the save that success before, it still works.  So I think my old save was broken or have some other problem, I will try those older save I backup before to see if any one still works., otherwise I think I have to start a new family with a new Scientist Career or keep the current family and change to another Career.

Thank you very much for your help.

Try resetting your user files as described in the factory reset described in this post: http://answers.ea.com/t5/The-Sims-4/FAQ-Troubleshooting-Steps-amp-Known-Issues/m-p/3621199

You won't loose anything. Just make sure to not delete any files  and make a backup.

Try on a new game with nothing added back first (start new game). If it works, put back your save game and try again. If it still works, you can start putting stuff back.

• Options.ini (or just re-set all your settings manually)
• Tray Folder
• Screenshots/Videos/Custom music
• Rest of the save games (leave out slot_00000001.save which is the autosave)
• Custom content like clothing, hair, skins, make up ....
• Mods (one by one, making sure they all still work)

The rest does not need putting back, cause they are mostly cache files that recreate or log files that are not needed for the game. 

Thanks, here it is

Could you post a screenie of the message ?

Hi, I started a new sims and a new save, but still cannot join the new sims to go to the Scientist Career. Let me try to reinstall again.

Could you start a fresh save and see if it works there.

Sounds a bit that maybe your science lot has corrupted.

If a new save works, would you be willing to share your broken save game ?

If so, please zip up this folder: documents\electronicarts\thesims4\saves and drop the file to this Mediafire-Link to upload.

No, I'm not using any mods in the game, and I had tried to repair before I uninstall and reinstall the game, but still cannot solve the problem.

Are you using mods in your game ?  If so, please remove them

See this for more information: [PLEASE READ] Usage of Mods and Custom Content

If not, have you tried repairing the game yet ?
