Unable to save new households or load existing ones

After downloading the latest update, i turned on the game and tried to load my last played household. But when i selected it on the map and clicked play, the game started loading and then, instead of letting me play, sent me right back to the world map without starting the game. I then tried to create an antirely new household to play with and the game didnt load it either, after selecting a lot for my sims to live on and clicking play, the game started loading and then gave me an error message suggesting i should reload my game and deleted my household. Same thing has happened even after reloading the game multiple times. Please fix this! The game is unplayable!
