Alwaysm at some point, fails "Error occurred while reading OPDS catalog". Sometimes it fails at the very top of the catalogue, other times, I can get some way in - subjects by title, most popular, etc. - but it always fails before I get to an actual book. I've never SEEN a book in my copy of CoolReader.
Uninstalled and re-installed - no change. Smsung Galaxy 2.3
