Have you tried resetting the doctor-sim? And/or quitting medical, getting another job, then after a day or two, quit that one and go back to medical?
The book you're referring to (Lady Raven Gothdancer or something like that?) is not part of Supernatural - it's a premium content item you need to purchase from the store. You don't need a magic book for your witch to reach level 10 of witchiness. In fact, the only new books that I'm aware of is the fishing book for toads/luminous salamanders/fairy damsels and the alchemy recipe books.
