I'm having a problem with Calibre on my wife's computer. I am not sure if this is the correct forum for this question, if not please forgive me and re-direct me as necessary.

Yesterday my wife started up Calibre and there were no books showing. A quick check of the folder in which the books are stored confirmed that they were all there. Neither of us have any clue what has transpired to cause this.

My wife's computer is a Mac Powerbook G4 running Leopard. She is using Calibre version 0.7.28. The library folder is on an external drive, a Western Digital "My Book." Everything has worked fine for months.

When I tried the option to change the library I pointed Calibre to the correct folder (in this /Volume/My Book/epub books ) and I get a box with a large X in a red square and the notice "The Location /Volumes/My Book/epub books contains the current library".

I tried uninstalling Calibre and installing a fresh copy. That didn't help. I finally changed the name of the folder containing the book, and set up a new one called epub books and installed all the book again. This time Calibre showed all of the books, although much of the metadata for the books had been changed. We fixed all of the metadata, connected her Nook Color, and everything seemed to work just fine.

Just a bit ago she wanted to add some books and started Calibre. Once again, no book.
I really do not want to go through the trouble of re-loading all the books again (especially if this is going to occur again).

What is causing this? How to do I fix it?
Any help would be greatly appreciated.
