Upsizing Wizard / SQL Server Version

I am attempting to use the Upsizing Wizard to convert an Access 2003 database to SQL on my desktop. The SQL server version on my desktop is:
“Microsoft SQL Server 2000 – 8.00.760 (Intel X86) Dec 17 2002 14:22:05 Copyright (c) 1988-2003 Microsoft Corporation Desktop Engine on Windows NT 5.0 (Build 2195:Service Pack 4)”
But when I run it, I get:
“Upsizing Wizard works only with Microsoft SQL Server (Version 6.50 SP5 or higher). Please log in to a SQL Server data source.” Why doesn’t the wizard recognize the correct server version?
