Hello All, I know very little about computers and in playing around with my Calibre I accidentally deleted all of my books. I have no idea how to restore my database. I looked in the user manual and it shows to type --really-do-it in the command line. One, i have no idea where the command line is, and two, i tried typing that in a text box a bunch of different ways and it just says:
