I have a laptop and a desktop. My desktop recently crashed and I had to put a new harddrive into it. Yesterday I downloaded Logos onto my desktop again. However on my desktop it says I have 1,108 books but my laptop says 1,116. I have some that were purchased for Libronix but I think they seem to be there. I ran update resources and there doesn't appear to be any books to be downloaded. How can I determine which books I am missing on my desktop?
