I just upgraded my OS and I was trying to reimport my library into Calibre but I'm getting this error whenever I try to direct Calibre to my old folder structure. It was on an external drive so nothing changed in that folder when I updated the system. I'm not sure how to get my library to reimport without having to copy my books all over again which will be a major hassle with 1,000+ books.
Here is the error:
ERROR: Invalid database: <p>An invalid library already exists at H:/Ebook/Calibre Library, delete it before trying to move the existing library.<br>Error: attempt to write a readonly database
RemoteTraceback (most recent call last):

Any help would be much appreciated. Thanks
