"servier isn't responding" status message

Back to my mac has worked for the most part for the past 2 years. I used it almost daily.

Ever since Moble Me has shut down I get this message. I use nothing but apple products. Airport extreme, Airport Base Station.

I haven't changed any settings, I have tried unchecking box, waiting 15 seconds like article http://support.apple.com/kb/TS4104 suggested.

Whats uP?
