BB 9700 doesn't sync with Ical

Hi, 

I have a BB 9700

My comupter is a MacPro , OS 10.6

My BB desktop software is 2.3.0

It was syncing fine before but i had to update everything and since then my ICAL dosen't sync. I need it to sync with my Calndar. 

I have installed and reintsalled it.

The error is  ""An error was encountered while syncing Calendars."" Please retry the sync.

But it doesn't work. Please email me at Renzo@creadorpictures.tv  or   renzodevia@hotmail.com

thanks
