Sorry I am new here and so have only just seen your question. I hope this still helps.
If the disk does not run automatically go into computer and select the CD drive. Select Explore to view the contents of the disk then select Launcher. This should start the installation process. My disk is version 2.2 but as I bought my reader in the US your disk may be a slightly different version.
I have purchased most of my books from Waterstones who have a good selection, but if you look round you can find a few sites that offer free editions, these may not have been fully edited but the book is complete. Unfortunatly a lot of the sites for ebooks only store them in title order and so it can be fun trying to track books by your favourite author.
Stick with it, my reader gets used for reading, audio books as MP3 music.
