> The same problem with invalid password. How to change it in the game?
It can't be changed from within the game. This was due to a change made on the EA server back in April 2011 or earlier. It wasn't that much of an issue back then because EA hadn't change the requirements for passwords to include stuff like mixed case letters, so a player could change their EA account password to match the Shift 2 password. A few years later, EA or possibly Origin changed the password rules, without any announcement of the pending change, and now players like me that had used all lower case passwords can't change the EA account password back, so now there is no way to log in with a save that has a password that doesn't meet the new rules.
As posted earlier, the situation is now worse. If you start over with a new save, and log in, you no longer get Limited Edition content, even though you paid for that content. The loss of Limited Edition content and promotional content like the Dr Pepper Camaro occurred around March 2018. It's been about a year since this problem was reported and it is still not fixed.
