I agree to try the work around that Jean posted. Sign into your
MDE account, then go to the very bottom of the page where there are links to other Disney affiliates. Select Disney Vacation Club.
On the previous version there used to be away to get yourself out of the asking for an activation code and that worked the couple of times I had that, but I haven't had that particular issue since they changed the website so I don't know if it still exists. It was a tiny link notation on the previous one that was easy to miss so maybe it's still there with this one? If not I recommend at least trying the MDE method.
