I updated to the latest daily build of Lightning and received the following error message: "Your Calendar data isn't compatible with this version of Lightning"   "The calendar data in your profile was updated by a newer version of Lightning, and continuing will probably cause the information to be lost or corrupted.  Lightning will now be disabled and Thunderbird restarted."
