ODBC driver problem

I have a Windows XP machine running Office 2002. I’m trying to create a mail merge with email messages…(I am trying to connect to a ISeries machine – AS400) for information to plug into the email. When I create an MS Query and tell it to select a data source…in this case my ISeries Connection, it will display a list of files(tables from the ISeries—so it is connecting and talking to the ISeries machine) but when I double click the file to select it I get the message…ERROR IN HOST SERVER DATA STREAM….The Help tab just states that this error was returned by the driver.
When I go to a Windows 2000 machine running Office 2002 I have NO problem in getting my connection and information, but it does not work on any XP machine that I try it on.
Does anyone have any ideas?

Thank You
Bill
