I am unable to login when I start up Sims 3. My worlds appear, and I'm logged in on here, and on ORIGIN, but I can't in game. It claims my login is invalid, though it worked yesterday, and everything worked to login on this site.
@Player_kfdomfcq Please try clearing the cache for Internet Explorer. Even if you never use IE, the game does for some purposes. Be sure to uncheck the box to presesrve data for favorites.
It's also possible that logins are not working today; the function is occasionally down for a few hours. But if you still can't sign in tomorrow, please post back, and I'll ask someone to look into it.
P.S. The worlds you've installed (and those that come with the game) should show up whether you're signed in or not. The ones you haven't bought yet might not be available through the in-game shopping experience, but it's never been necessary to be logged in to use your installed content.
