Subscribed Calendar Events No Longer getting to Calendar.app
About three days ago--perhaps following the latest update to 10.8.2--the events in my wife's calendar (to which I'm subscribed) stopped appearing in iCal. They are still appearing fine in iCloud.com and also on my iPad and iPhone. However, in iCal on my iMac running Mountain Lion, the calendar shows in the left hand column but none of the events show up no matter how often I refresh the calendar. I tried deleting the calendar from the iMac and re-subscribing, but this has not helped. In fact, the Join This Calendar button on my wife's "subscribe to" email dumps me right into iCloud.com on Safari. I tried right clicking the Join This Calendar button in her email and copied the link into a new subcription in iCal, but an error message popped up saying the link she sent me was not valid.
A further problem is that events I've created in my own calendars on the iMac are not being uploaded to iCloud and the other devices, although I'm getting events created on the iOS devices coming down from iCloud into the calendar on iMac. Very strange problems.
I'm stumped about what to do and am always very cautious about making changes here since I've caused myself big problems in the past by deleting calendars to correct problems only to have them totally disappear, requiringh fairly major surgery and Time Machine to get things put back together again. The changover from MobileMe to iCloud was particuarly messy in this regard.
Any ideas.
