Blind readers: has anyone successfully used Bookshare's Bookshelf and Web Reader tools?

I added a book to my bookshelf, but now I can't seem to get tot he bookshelf, which I would like to delete and start over. I keep getting an error message which keeps suggesting that I go back to the support center.
As for Web Reader, I have yet to find a "Read Now" button.
I have the feeling that the FAQ has left out some important steps. Thoughts?
