Re: Everything missing from My Library

I am on PlayStation 4, the exact message in history is 

Date 12/2/1022 12:45:04 am  

Error Code CE-34878

Application CUSA09209

NAT Type Type 2

System Software 10.01

Message An error has occurred in the following application. (The Sims 4)

I don't know if you would need the other information but I added it anyways. I looked into getting PlayStation plus to recover my files but don't currently have it. Is there anyway of knowing if the files are also corrupted before buying? Also would recovering these put my game at risk? What might I've done to cause this and what can I do to prevent it in the future?

Thank you so much, I really just want some answers so I can play again I've been too worried to open my game in fear of causing more problems and losing even more.

If you don't have PlayStation Plus already, your save files wouldn't be stored online to recover, that feature is only for PlayStation Plus members. 

If this error message continues to pop up for you, I'd recommend running through the steps here to help clear this up. 

As for the corruption in your save files- if they haven't been stored online, we won't be able to recover them unfortunately, they'd need to be deleted I'm afraid. 

Corrupted save files can occur as a result of a connectivity issue or power loss when the game save file is being created. This can also happen if the console is powered down while still in the process of saving. 

In the future to prevent this, I always recommend waiting a minute or two to close the game and power off your console after you've saved so the game has sufficient time to complete the save. In addition, if you have a large number of save files, you may have reached the capacity limit for saves on your console storage. Try reducing the number of save files to be sure no other saves become corrupt.

I've had PlayStation plus in the past could anything have been saved as a later version there? Also it was a problem with my library not a save but the error did happen in a save, the game didn't delete that save just everything in my library, do I have to delete that save myself or can I keep it? And after I've done everything is it okay for me to play my game again.
