I don't know what to do to get my Calibre library back.
I have tried restoring my Calibre library from backups, and either get a message that no valid library is present when I try to switch libraries in the Calibre app, or, it seems to import my backup library, then shows zero books.
I have attempted this restoring while Calibre is closed, per earlier instructions. I end up with multiple Calibre directories that I didn't create.
I don't know what exactly I did to create this mess, but the more I try to fix it, the worse it seems to get. I have the ebook files on my computer, it's just trying to get them into a Calibre library that I am having problems with. Have spent more time than I want to admit trying to fix this.
I just want to restore or create a working library in Calibre. Is there not any way just to start from scratch?
