Ok let me see if I can make sense of this, I make my own books from LIT files and TXT files that I get, as of late I have been using ebook reader to read, and DropBook to make my books. I had about 30 books and just recently I added about 30 more, I have a lot of free time on disability. So for some reason all the new ones that I have added keep coming up with an error saying that I need eReader Pro to open reference material. Its not referance material, they are just novels. So I have been doing some research on T|C and I saw someone using MakeDocW. I made some of the new books again with this utility and they worked just fine. Anyone have any ideas? I use the free version of everything. So I am just curious, what do you guys think?
