I have been using Calibre for about 2 years and absolutely love it. I keep my ebooks on an external hard drive. I don't do anything fancy and only open Calibre to peruse the titles and synopses and decide what books to download to my tablet and to add new books to my library of a couple thousands of titles. Each time that I open the program I usually get a notification that a newer version is available (great job, developers!) which I would religiously install until a few months back when I was told that the future releases will no longer support Windows XP.
I recently migrated to a Windows 7 PC, and having kept my Calibre library on an external drive I thought I would be I thought I would have no problems. When my newly downloaded Calibre started and was pointed to the old library, I was notified that the database was corrupted and needed to be repaired. It went through three passes only fail at the very end.
Help, please.
