Eh... Not sure how to describe this...

This is weird.....whenever you change your password on the site,the password in the game automatically changes aswell.

You're password needs to be 16 characters.

Just popping in here to say that's not true xD If your password is longer than 16 characters, it won't work. But that has to do with the 'Invaild Username or Password" message. I am honestly not quite sure about changing your password anyway. But that's not that issue here. I don't really see the 'logged out by another user' message quite often, but there are a few possible causes:

1. Someone guessed your password.
2. Do you have siblings? I've heard of the game not liking it when two accounts are using the same IP address at the same time (though I personally have no problem doing this)
3. The game could be mistaking you losing connection for you being logged out by another user maybe? Is your internet connection stable?

Anyway, I'm not quite sure, and this is all I can think of. Hope you figure this out.

Your password doesn't need to be 16 characters ^.^

And that happens if someone else logs into your account - you get automaticlly logged out.
I'd change the password - just to make sure noone else cracked it somehow.

Just an idea-- Do you have another computer? If you do, try using that... If you have Feral Heart or can download it on that computer.

Umm... This is very strange. It should usually change automatically on the game too...

Maybe someone guessed your password. Or maybe you keep your login in a book or something, And one of your siblings found it and used it on their laptop?

But either way, This is very strange. Sad for you in fact.
