MySql SetUp

Hi,

I transferred a VB6 application using MySql 3.51 Drver From Windows 98
platform to XP. I downloaded MySql 3.51 set up the ODBC driver connection
(User DSN). The VB6 application runs great however, when I update a record
(.Update) I receive run-time error -2147217864...row cannot be located for
updating etc. What am I doing wrong?
