Did you move iCal out of your applications folder? That can cause it to get to miss an update when you upgrade your operating system. Make sure it is in your Applications folder and then upgrade your operating system.
If you have 10.5.7, you can upgrade to 10.5.8 free, and 10.6 might be free depending on if you are on Mobileme. See this tip.
