Memory issues

[MSNEWS]

I'm having problems using the word.applicationclass to load a word document.
I've created this very simple code and I get the error below on the
WordApp.Documents.Open("C:\temp\worddocs\1.doc", 0, 1) line.

An unhandled exception of type 'System.Runtime.InteropServices.COMException'
occurred in test.exe
Additional information: There is insufficient memory. Save the document now.

This is my full code!
Please help, this is getting annoying.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click

Dim WordApp As New Word.ApplicationClass

Dim contentsofword As String

WordApp.Documents.Open("C:\temp\worddocs\1.doc", 0, 1)

WordApp.Selection.WholeStory()

contentsofword = WordApp.Selection.Text

WordApp.ActiveDocument.Close()

End Sub
