Google recently made a small change to their online feed reader which broke the Awasu synchronization plugin. An updated version is now available so if you're using this plugin, please download it again and unpack the ZIP file on top of your existing files (e.g. C:\Program Files\Awasu\esync\).
If you're not using this feature already, you might want to check it out. Sync'ing Awasu with Google Reader, Bloglines and Gregarius is definitely way cool 😎
