Hey there,
Did you happen to try installing the game from the original disk? The installation process has changed a lot since the game launched and installing from the disk may cause problems nowadays.
If you did, check out the info in this post below and try the steps there.
If you are still getting the error, are you able to log into other regions? For example try switching to the Europe region before hitting Play and see if that lets you log in without the error. If it’s only affecting on specific region I’d recommend submitting a ticket and including the details so we can investigate further.
