Upgrade to latest version broke code

The following was gold code until I upgraded to the latest version. I was previously at 2.x which I bought in July of 2005. I have included the small sub where the error occurs and the sub that calls it directly below it.

I am simply copying a word document that is a template and then merging in data for each person being mailed and then merging an undetermined number of photos belonging to each person. The final document is the target document.

Private Sub AppendDoc(ByVal dstDoc As Aspose.Words.Document, ByVal srcDoc As Aspose.Words.Document)

While srcDoc.Sections.Count > 0

Dim section As Aspose.Words.Section = srcDoc.Sections(0)

'The section must first be removed before it can be inserted into a document.

srcDoc.Sections.RemoveAt(0)

dstDoc.Sections.Add(section) 'ERRORS ON THIS LINE

End While

End Sub

My bad. I forgot to include the error message.

I gave going through the documentaiton a second try and corrected the sub as follows:

Private Sub AppendDoc(ByRef dstDoc As Aspose.Words.Document, ByRef srcDoc As Aspose.Words.Document)

Dim srcSection As Section = srcDoc.Sections(0)

Dim dstSection As Section = CType(dstDoc.ImportNode(srcSection, True), Section)

dstDoc.Sections.Add(dstSection)

End Sub
