Resolution
If you receive this alert, try these steps:

- Repair permissions and verify your Mac OS X volume with Disk Utility.
- If this does not resolve the issue, perform an Archive and Install installation of Mac OS X 10.4, preserving user and network settings. Afterwards, update Mac OS X with Software Update.
