After I updated to 10.5.2 I'm having a bit of trouble syncing calendars with .Mac on my PowerBook. I tried everything I can think of: ONLY syncing calendars, hiting the "reset sync data" button and then replacing information from .Mac to iCal. No matter what I try I always get the same error message: "Calendars could not be sycned due to inconsistent data. Confirm that your computer's data is valid, then rest Calendars on .Mac in System Preferences." I know it's just calendars because I tried syncing it with the calendars option unchecked---it went through perfectly fine. Anyone have any suggestions on how to fix this? If I even knew how to just delete all the calendars from iCal, that would be fine!
