Can't log in to Sims 3

I can't seem to log into the sims 3 through the launcher or once I've loaded my game. I wanted to be able to dowload my purchases from the sims 3 store but can't log in anymore. If in game and I try to log in it tries to connect but then an error pops up - 'connection to the server has been lost'. If I try to login through the launcher it completely crashes. I am able to login to my ea account and the sims 3 store but for some reason I can't in the sims 3. Does anyone have any suggestions? I've tried clearing caches and re-installing the game.
