Calendars could not sync due to inconsistent data

Hi all
I am getting a warning when I sync my iphone /mobile me / computer i cal.
warning appears saying
"Calendars could not be synced due to inconsistent data ' - confirm your computers data is valid then reset calanders on mobile me in system preferences'

Sounds easy, so i go into SP/mobile me/sync/click calender/advanced/reset sync data/on this computer with sync info from mobile me.
Then is fails with the above error message.
Its really annoying...
so if I add an event on my iphone i cal it does not sync with my computers i cal, and If I add an event when I am on my computers i cal it wont sync with my iphone.
anyone experience this as well? any way to fix it?
Thanks in advance

Macbook, Mac OS X (10.4.11)

I have the same issue. And if I add an event through the web version of iCal on Mobile Me, it does not add it to any of my syncing computers or iPhone calendars...

Finally figured out a fix:

1) Go to System Preferences and Turn off Calendar synching in all the computers. (Leave synching on for other features: bookmarks, etc.)
2) If one of the synching computers does not give the "Calendars could not sync due to inconsistent data"" message, go to the System Preferences>Mobile Me>Advanced. Click Reset Sync Data, select Replace: Calendars from pop-up menu. Click on arrow under the Mobile Me cloud icon and click Replace.
3) Turn calendar synching back on in all the computers. Next time they sync it will ask if you want to merge or replace info. Select Replace.

Some recently added calendar information might get lost in the process, but syncing will work again, conflict free.
