It's possible that something when wrong with the configuration of Palringo itself - try clearing Palringo's settings. To do so, make sure Palringo is not running, then go into your ~/Library/Preferences folder and delete the com.palringo.Palringo.pList file.
The next time you will start Palringo, it should be as when you installed it for the first time.
