error in admin_register With MySQL

Hello,
I use Web Wiz Forums® version 9.60 With MySQL 4.1.16 database
When I update a Member I have this error with all the Members:

Microsoft OLE DB Provider for ODBC Drivers error '80004005'
Query-based update failed because the row to update could not be found.
/forum/admin_register.asp, line 399

if for example  I use this method found the row

    strSQL = "UPDATE tblAuthor SET PM_notify=-1 where Author_ID = 16 ;"                                             
    adoCon.Execute strSQL

As can I  resolve This problem?
