Hi Jackie, I detected an error in the program when we customized the plugin options and checked the embed option in each MP3. The problem is that if I am converting several books at once to MP3 format, the images of the covers of the different books in each of the folders that are created are mixed. You can see it yourself in this screenshot, although the same thing happens in all the folders. To avoid this, you have to do it one by one and wait until the process is over to start with a new book.
