I've got the latest 3.3 Sony Reader Library installed. When I go to the Store I'm having trouble with the search function returning errors, and no results. Clicking on many links also returns errors. I do not encounter these problems if I view the Store via a web browser, but you have to have the Sony Reader Library software to purchase books. It took me about 15 minutes to manipulate the store pages just to get to where I could purchase The Lord of the Rings: 50th Anniversary, One Vol. Edition.

I'm also noticing that the fonts used in Sony Reader Library are really terrible in Windows 7. They look like old bitmapped fonts and are not easy to read. I know this software has never been very good, but at least it used to be functional as far as buying books.

EDIT: Sony seems to have fixed the search and links problems.
