Version 1.0.3 brings a fix to the auto-update routine, so you will need to apply this update manually by downloading the latest version from your Account area.
I’m also recommending that you purge and reindex your content. A change was made in the handling of some special characters that might have an effect on some of your searches, so the easiest way to get around any potential issues is to purge the index and start fresh.
