Kobo Aura HD and Adobe Digital Edition

I have been using Adobe Digital Edition for almost a year with my Kobo mini ereader.  I had problems when I first started using my mini but after a long discussion with one of your people, the problem was solved and I have had no problem downloading library books. 

I have now purchased the Kobo Aura HD and when I tried to download library books I got the following message:  CE copy not allowed - no permission to copy the book.  Which is exactly the same message that I was receiving when I first connected my Mini.

Can you fix this problem as well.
