Sync Problem iCal(write protected) to BB9900

Hey,

I�ve got a new Mac yesterday because the old one was done (only 2 years old though...). Anyway, I connected my BB as usual to the computer and started DM and tried to sync it with my phone.
I noticed that I can�t sync my Calendar with my BB. It�s saying that there is write-protected calendars on my computer for syncing. Start iCal or ME and create a new non write-protected calendar. This is new and I have never seen that before. I really want to sync my BB to my calendar because I would like to have all the events I have on my BB also on my Mac.
Don�t know what went wrong or what is different to my Mac before. Does somebody know how to fix that?

Nobody know how to fix that?
I mean it worked before. It is practically the same computer.... why not anymore?
