Removing last line in header

[narmi2]

hello

I have the following code which reads a file into the header

Dim oSec As Word.Section
Set oSec = ActiveDocument.Sections(1)
oSec.PageSetup.DifferentFirstPageHeaderFooter = True

oSec.Headers(wdHeaderFooterFirstPage).Range.InsertFile "C:\Program Files\Microsoft Office\Templates\TheHeader.doc"

but this leaves an extra line under the text inserted in the header. How do I remove that extra line in the header?

thanks
