I just started having the same problem on a PC using Windows 7 64 bit. Yesterday it went totally unresponsive. A soft boot didn't help. A hard boot got it working again. It happened again today. I use Reader Library 3.3 - the latest version.
I contacted Sony CS and they thought it was my anti-virus software. McAfee just did a program upgrade right before the problem started. Thus, maybe their next upgrade will fix the Sony Reader Library problem.
