This error occurs whenever I try to play The Sims 4. I've tried re-installing the game, and nothing changes. I have custom content in my game, and I moved all off it out and it still had the error. Some other people suggested deleting cache files and running CHKDSK and such but nothing works. I am a Sims fan at heart and have been devastated because my game has been like this for over 3 months and I really love the game. I don't want to restart my whole Sims game because I have done so much progress, and I have already tried something which ended up in me losing half of my custom content. Please help!
Edit: I've also tried "http://sims4.crinrict.com/en/2014/09/resetting-the-game-to-factory-settings-without-reinstalling/". I renamed my Sims 4 folder to "The Sims 4_Backup" and when I tried to play the game, it still had the same error.
