iCal Calendars Disappeared

On my MBPro with Moutain Lion, I had an up-to-date iCal with several calendars.  However, when I tried to use the calendar recently, all of my calendars had disappeared and iCal was set to 2013 and completely blank!!

I do have another calendar on my iMac which I imported but it is not up-to-date.

How do I restore my previous iCal and calendars?

I do have a recent clone made by Carbon Copy but I can't find iCal or calendars.  Can you tell me how to find them on the Carbon Copy Clone?

I recently ran Disk Uptilities to repair permissions since my MBPro was slow in waking, so did that cause my problem?  How do I remedy that?

Thanks for your help.
