Woke up this morning with to find three copies of all my iCal calendars without explanation. I deleted two on home MacBook Pro. I got to work with MacBook Air and all but one (of eight total) calendars are gone. They do not appear on MobileMe either and folks with whom I share the calendars can no longer access them. Is there any way to retrieve the information? Last backup was two weeks ago, the information entered since then is pretty critical. Thanks for any insight.
