When I click on my sims household it takes me to manage worlds what do I do!?!?!

If you have the old MC Command Center installed the game will take you the the manage worlds screen and you wont be able to load any saved lot, you need the most recent update for it after the Seasons update: then the saved lots will load: or you could remove this mod completely. You also need to update WW if you want that mod to work.  The testing cheat codes on the other hand are not all working (not the most important ones anyway).
