Thanks for the reply, I did exactly what the video showed and it still doesn't work. I have tried this on 2 different computers with no luck. I found one for $35 but I'm hesitant to spend that much for converting 4 books and I'm not sure if the site is safe. The demo of that program worked, but it only converted 3 minutes.
Here's the link: Tuneskit
Does anybody have any experience with this program?
