There are lots of bugs in ADE2.0. Try replacing ADE2.0 with the older but more reliable v1.7.2.
(You can have them both installed at once if you like.)
Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.
The forum software is sometimes corrupting the link above. There shouldn't be a blank in 'editio ns.html'. The following redirects to the same page: http://tinyurl.com/diged172
Thanks for the effort. I downloaded the older v1.7.2, however, it also refuses to load a bunch of books at one time. I have 780 book that I would like to load - or as many of them that the progam will hold - . The mind boggles at the thought of adding that many books one by one!
I used to be able to load large numbers of books in one of the older versions, can't remember which...
But thanks anyway.
OK, thanks, should have thought of it before. I see that my Kobo reader can be loaded via Calible so that's going to work for me.
