I kept getting this error so I went out and bought the ultimate game cards. This worked for me. I just think it's stupid that if you screw up once it locks it for 24 hours. It should be 3 times at least. I also think that they verify you using your IP it's just a hunch because my husband and I play and they probably think we're gold farmers because we're coming from the same IP. If an entire family plays I have no idea how that is going to happen. If someone has more then one person playing this game in their home have any of you been successful with getting all accounts to work?
