Merging Authorizations

In May of 2014, I move to Vancouver, Canada from Quebec City, Canada.At that time, I got a new email address and cancelled the one I had in Quebec City. In 2015 I moved to Ottawa, Canada and kept the same email address.

At that time also, I updated my Adobe account to the new email and reauthorized ADE on my desktop computer, my iPad and iPhone with the updated account.

Since early December I can't download DRM books on my iPad. It had been working properly for years.I reauthorized the iPad, deleted Bluefire Reader, and turned off the iPad.I then restarted the iPad, installed Bluefire Reader, and tried to authorized it.
It wouldn't accept my Adobe id and password. The message below shows why. What is to be done to get Bluefire Reader to work?
