XP SP2 Install Failure - Catalog Files

After successfully upgarding to the beta verison of SP2, I am now unable to
install the final release. The install program goes through the inventory,
backups and restore point phases then crashes out with failure to install
catalog files.
The only KB article I've been able to find is 822798. I've tried all methods
bar the last two and have had no success.
I have also tried a repair and re-install of critical patches but hat also
had no effect.
The following is an extract from SVCPACK.log.

Any advice will be welcome.
