After installing 10.5.2, iCal won't load (attempts and immediately quits). Anyone else having this problem? Any suggestions as to how to resolve the problem??

I tried your recommendation but iCal still doesn't fully launch. Getting worried. 🙁
Hmmmm. Tried dragging the Calendars folder from the Library to the desktop and relaunched iCal expecting to see blank calendars (if anything). And instead got back everything except some viewing settings! A surprise but a relief. 🙂
For those having problems with iCal post 10.5.2 upgrade, delete the cache files from [User]/Library/Calendars. iCal will then automatically upgrade your calendars.![]()
What you actually got is the version of the database you had before upgrading to Leopard it still sits in ~/Library/App Support/iCal
For me unfortunately, this is already more than two months out of date 😡
