How do I recover a corrupt .pst file if scanpst won't open it?

[Eric]

Outlook 2000 locked up so I closed the program and restarted windows. Outlook
wouldn't open the >pst file so I created a new one and tried to import the
old one.
I get the error message "Properties for this information service must be
defined prior to use" followed by an access denied message on the PST

I have verified that the file is not checked as Read Only.
I have verified that I have full control of the file
I have tried to make a backup of the PST but it won't let me copy the
file anywhere as either the user or administrator. Although I can not
copy the file I can rename the file and I can move the file
I tried to burn the PST to a CD but get an error message that the file
has been changed or deleted. Yes Outlook was closed
I tried running ScanPST but got an error message that an unregistered error
prevented it from accessing the file
