Unable to transfer ebooks to my sony prs 505

Since I bought my new laptop with windows 8 I have had unsolvable problems and can still not transfer an ebook to my sony prs 505. I am having assertion failure, port error messages and licensing error messages. Can I please talk to someone over the phone so I can describe what is happening. The last time someone helped me by sharing my computer I had 190 talk windows that I had to close manually.
