Crash in Office 2000 - works in 2003

I have made a code that works fine with me running Office 2003, but
crash in the customers setup running Office 2000 and only RunTime
Access 2000. What do I need to change?

The code is run from a form module in Access trying to connect to a
Word-document:

InsertField

Feil:

End Sub

Private Sub btnNewJournal_Click()

Me!Journal.SetFocus

With Me!Journal

If .OLEType <> acOLENone Then
MsgBox "There is already a journal."
