I just drove an hour this weekend to get a card at the only set of libraries in GA that offer ebooks (everyone offers audiobooks). So, I get home and the pubs had worked before, but I couldn't get them onto my computer. It downloaded a link, but not a book.
So, then I find that I have to right click on the link and click on unblock to actually have it download the book (this is a VISTA issue I learned) after having closed adobe. Then, I can open them on my desktop and move them over to the reader, but I can't open them on the reader.
Then, another google search led me to deauthorize the sony reader, unplug and then plug back in the reader and re-authorize it. What a hassle - but I am now reading library books.
