How to get rid of an error message on ML

Hello,

Since updating to ML every time I enter my password to log-in on MBP, I am seeing an error message with the yellow triangle and white exclamation point that appears for a matter of seconds and then disappears. This message comes and goes so fast that I cannot even read it!

How can I make this error pop-up go away? I am tired of looking at it when I boot up my computer!
