Hi

I have no idea if this is the solution but it is worth a try: From BooksOnBoard

Error: "Adobe Reader could not open because it is either not a supported file type or because the file has been damaged." If you are getting the above error message, it means your computer is attempting to use Adobe Reader to open a secure ePub or PDF book. Secure ePub and PDF books are only compatible with Adobe Digital Editions (ADE), they will NOT work with Adobe Reader.

If you don't already have Adobe Digital Editions, you can download it from the Adobe website here: http://www.adobe.com/uk/products/digital-editions.html
