Re: Sims 3 can't login to launcher
@ptwing711 Did you specifically clear Edge's history, or at least its Internet Explorer-mode data? That's what the launcher and game use regardless of your computer's default browser.
As a test, please create a new admin Windows account and try signing in there. This distinguishes between problems limited to your main account and more global ones.
Please also let me know what happens when you try to login at each stage. Do you see an error that says the login is invalid, or does nothing happen at all except the login button shows up again?
Getting extra SimPoints is a longstanding glitch with the Store and is unrelated to this problem. Have fun with the free points.
