I already solved this once... the cause of this is because you are messing with the nw.js ( formerly you used one with your former save state then updated the nw.js so the game logs in that change has been made... nothing life altering but if you wanna get rid of it follow these steps ! )
Go to User\User Name\Appdata\Local ( hidden ! )
Delete the folder nwjs
Go to User Data then to Default... Search for Web Data and Web Data-journal and delete them
Launch game anew
Do not mess around with files if you don't have to ! I don't think that upgrading the nw.js was necessary...
