I need some help getting books onto my Ebookwise..I'm using EBWLibrarian on my computer and I've finally successfully imported a book to my bookshelf and got my Ebook connected to the internet etc, after many problems.
It now recognises that I have a book on the online bookshelf and shows up fine on the computer but the Ebook, when I click on the 'online bookshelf' part, comes up with this:

'Although there is an eBook on your eBookwise Librarian bookshelf, it is not suitable for this device
Please try again with another bookshelf or create some eBooks formatted for this device'

The book I'm trying automatically was converted into .imp..so what's the problem? I've tried everything..except making a new bookshelf, how do I do that?
Plus, I put the book in a category as it says I have to but I made up the category, it's not like I made a new one on the actual eBook, is that possible and could that be the problem?

Thanks in advance for any help!!
