I've been having problems in the last month transferring books from ADE 3 (I've also tried 4.5) to my Kobo Touch. Everything appears to go normally but when I eject the Kobo and look for the books, they're not there. However, if I try to do the transfer again, ADE says the book is there and asks if I want to skip, duplicate or replace. I've tried both of the possible options and nothing happens. I've tried doing a reset on my Kobo and reinstalling everything and it still doesn't work. I've had my Kobo since 2012 so perhaps it's just come to the end of it's useful life. I use it mostly for reading books from the library so this is definitely a problem for me.
Any help appreciated.
Update: I have now done everything including the manual factory reset on my Kobo and it still doesn't work. I don't really want to buy a new one if this is an Adobe problem.
