I'm having the same problem as Aiden. You see, you can't access line settings if you can't login to Line. I have no mobile device and both Aiden and I are on pc's running widows 8. I am running windows 8.1, but I think registering for 8 & 8.1 are the same. They say you can use "line" on a pc without a mobile device, but I'm beginning to believe that you.
can't.
