Hi Bob. Yes, I downloaded the most recent version. I can open the eBook Library, and go to the store. When I click on 'Register' I always get the error. I can go to Login and put my user name and password, however when I hit submit I get the error screen again. It's so frustrating since it seem like the eBook Library is the only place I can buy books for my Sony Reader PRS-505. So now I own a $300 gadget that does nothing but let me look at the book excerpts it came with.
