Ok this does not happen all the time but it happens enough to be pretty annoying. I start my pc up login and play for awhile and everything is fine. Then i exit the game for awhile and leave my pc running. After some time i go back to login and play but it gives me an authentication error saying wrong email or password. When it does this it will keep saying that till i restart my pc. After i restart the pc, it will let me login. anyone have any ideas why??
