When I started SHIFT 2, the game tried to connect to the Autolog servers, as usual, but it would always give me the same error: Password Invalid. And since there isn't any option in the menus to insert the new login, I was stuck with that stupid error and I couldn't connect to Autolog!!
After some searching I found that if you change your EA password, some games might stop working, SHIFT 2 being one of them. There is no way to change your login in SHIFT 2, at least without losing all your progress. If you delete your savegame, then you will be able to create a new login.
The solution is to go back again to the old password you had. I did that and SHIFT 2 worked all right. However, this is a massive fail IMO, and the next patch better fix that. I really want to change my password at EA before they get hacked too (you never know, they might be the next ones in the list).
So this serves as a warning if you want to change your password and own SHIFT 2: don't do it.
