When I click on Calibre Library, then Switch/Create Library, a pop-up says:

Read Only Error; attempt to write a read-only database.

I don't know where this database is, and I am not sure where my Calibre library resides, or if I messed it up, or maybe I just have an e-book list.

I was attempting to create a new library with the ebooks I have.

Thanks for any help.
