So yesterday i was playing the sims 3 like normal when the game crashed. i was logged into the sims 3 like normal til it crashed. when i loaded the game back up it was supposed to automaticly connect to my information but instead it said it was invalid. i checked the sims 3 website and it said the password was fine but when i went into the game it said it was invaild. and then today i was playing without being signed in cuz it wouldnt let me and now the launcher says it cant connect to the website. so i dont know what is going on now. everything was fine until it crashed on me. then i started having these 2 issues.

@simkitten87 Try clearing Internet Explorer's cache. Even if you never use it, the launcher does for some purposes. Be sure to uncheck the box to preserve data for favorites.
If that doesn't help, try changing your password (using another browser) and clearing IE's cache again.
