I can't use any of this information as iCal will not even open on my Mac. It just has an error log.
I cannot open iCal on my Mac. I simply get an error log. I try to "re-open" and the same error log displays. I've turned off the cloud. I've turned off my iPad and iPhone. I've re-started my computer.
iMac, OS X Mountain Lion (10.8.2)
