I saw the same issue on my wife's account....where we didn't resubscribe but now it show 'SETUP COMPLETE'. Not sure why this is happening, I thought maybe because we had used our code for the cancelled St. Louis JT Show, that maybe U2.com just reactivated it since I used it on a show that didn't happen. But if others are having this issue, I guess its probably an issue with U2.com acounts. It gives me very little hope that the presales will go smoothly, but hopefully this is the only issue they have.
For those affected, I would error on the side of caution and resubscribe. This way
