Can't log in through Sims3 Launcher

Hello,

Has anyone had any issues logging in to the launcher?

The launcher won't let me sign in, and it won't save my account name or password. I enter the information, the prompt closes, and goes back to the launcher screen. I've reset my password, and reinstalled the game and expansions. I have no issues signing in to the Sims3 site or store. The game is at the latest patch. I have no other issues with the game. I can't access any of my store content now because I can't log in.

I have emailed tech support, but haven't had any useful advice.

Thanks
