As previously stated, by many other users. I cannot log into the Steam version of the game currently. It hardly seems fair when the issue of logging into your account is completely out of your control. No one else is subject to this kind of hassle. And these problems are not even talked about by SE. There is never any posts about this kind of issue.

Either revert the changes that force the Steam version to have steam running while playing. Or let us convert to a Windows Account. This is not the players' fault. This is ENTIRELY on SE. And they Need to fix this.
