Thanks for your reports!
To help us investigate this, would you be willing to send us some information? If so, and if you haven't tried already, please, reset Internet Explorer:
If you are still unable to log in at the Main Menu after doing that, but you can log into the launcher and thesims3.com without issues, please, send me the following information by direct message, so we can investigate the situation:
Please, make sure to send this information by direct message - don't post your private information on the thread as this is a public forum.
PS. In case anyone is wondering: I've merged a couple threads about the same in a single one to keep all the information together.
I am having exactly the same issue. I am able to log in at the first screen, then I click the play icon and after loading it says incorrect e-mail or password. I enter the correct info but keep getting the same message. Sometimes it works after two or three attempts, other times it does not. I have never had this issue before. I dont know why IE is involved? I use Chrome.
Ok have just reset IE as suggested - now the game wont work correctly!
Once the game loads the first screen no longer shows the account log on, just a message that says it can't display the web page correctly. Then when I click the play button, i load the game and I still can't log on. And now it no longer recognises the DLC - ie world adventures, etc. I can run the game and can't log on from within it either.
Any ideas anyone?
@RadioMan71 Based on your description, it sounds a lot like your entire TS3 game folder in Documents was removed or deleted. This would delete your saves as well as your store content—all of this data is located in your game folder. When TS3 can't find this folder, it spawns a new one, but this clean folder won't have any of your content.
If you didn't get rid of your game folder yourself, it's possible that it was automatically uploaded to OneDrive. You can retrieve the folder from there and put it back in Documents\EA, but of course be sure to remove the newer folder first. Then disable OneDrive so that this doesn't happen again.
You don't need to be logged in, or even connected to the internet, to use your store content while you play. I myself disconnect from wifi before launching TS3, and my content always loads just fine. Of course, if you play through Origin, you'll need to sign in first, but you can then put Origin in offline mode and turn off your connection before loading the game. The only store function you won't see is the in-game shopping experience, but it's better to turn that off anyway, as it's a drain on resources that your saves need for themselves.
And yes, it's possible to decline to login at the Main Menu, then do so once your save has loaded. It has no effect on the save itself or any content in your game folder.
