The sims 4 Cannot start because of missing or damaged data

At least the game is opening now.  It's acting like it's completely new, but I don't know if that's part of the "repair" deal or not.  If not, I noticed that the game created a new Sims 4 file.  Luckily, I still have the backup file, so (correct me if I'm wrong) I should be able to delete the old file and play from my backup with my old sims.  I am going to try tomorrow, since the computer is struggling to stay on after working so hard.
