If you want to play a book you must import it first to DreamPath Storyteller.
You can import books in 2 ways:

1. Double clicking on the book file (*.DPS) will automatically import it.
2. From the main menu: Organize Library --> Import Book, then choose the book file (*.DPS)

Once a book is imported you can always play the book (no need for the book file)

* When importing a freeware book if a message will notify you it's freeware. If you paid by any means for it please contact me via email. (Which you can find here)

* Warning: Messing with DreamPath folders is not advised. it is not possible to import a books simply by moving it to the right folder.
