Hmm. I think I remember having an issue like this a long time ago on another game forum. I don't remember how I solved it, but here are some things you can do.
1. Try logging in and out again. But reading above, I see that it has not fixed.
2. Try clearing out your files, in case some sort of bug slipped in.
3. Go back on your girlfriend's laptop. See if the glitch is gone. Sometimes if you log on to a game, it authorizes one computer and unauthorizes your previous one.
4. Though the Feral Heart forum is usually the way to go, if all else fails, just try Google. Maybe someone has experienced the same issue and know how to solve it.
This is really all I have. I'm sorry you can't operate your account properly, and I hope it gets fixed soon. Hope this helps!
