ICal crashes after migration from G3

Question

Hi - I just took over my boyfriend's G4 laptop after having a G3 "snow book" for years. We erased the G4 HD, reinstalled the software that came with it, used the migraiton routine to move stuff from the old G3 and then upgraded to 10.4.11. Everything is working except iCal.
iCal crashes immediately. The icon will bounce in the Dock, the calendar will appear and then disappear. I've been prompted to "Report to Apple" and I've done so at least 3 times.
How can I overcome this? How can I get iCal to work?
TIA some expert info,
lefty

Hi lefty, and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Tiger Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If that doesn't help, quit all Applications, try moving these 3 files to the desktop and reboot...
