"Thank you for registering"
Do you mean "Thank you for logging in, MADISON"? You shouldn't get any thanks messages at this date for registering 10 years ago.
The most likely culprit is/are your TFL cookies. The cookie structure changed recently, so it would be a good idea to delete them all and retry.
Another, but less liekly, reason for the that message is when users use the AOL native browser - don't.
