Thanks for the suggestion. However, I have tried to log in on multiple computers, even ones that I've never played the game before on. I've tried it at multiple houses. Also, it's 2 out of 4 accounts that we have, so it's not all of them, which would make me think it's my computer.
This error is
not associated with a certain computer, it is associated with my
account. Therefore, it doesn't matter who logs in, or where. It simply isn't going to allow me to play the game. I'm already way behind now, as I haven't been able to play any of the June Update at all. I'm keeping up on my daughter's account, though. She's letting me do it, so at least I can play on that.
