The Vendor account entered is not associated with the item you are trying to open

Hi

I moved from a Windows laptop to a Mac Book pro and moved all my files across, now I have found that two of my purchased books I can no longer open, I always get "The Vendor account entered is not associated with the item you are trying to open" message, I have the correct authorisation but they do not open, is theer a way to recover these 2 books?

Thanks in advance
