Hi Jade,
I think the script had a few spots that were not compatible with SQL 2000 and only worked in SQL 2005. I've corrected those issues and replaced the download file. The only file that changed in the new download is webroot/Setup/applications/mojoportal-core/SchemaUpgradeScripts/mssql/2.2.3.6.config
I've sent you this file as an attachment. Please let me know if it resolves the problem.
Thanks,
Joe
