word macro split file on delimeter - vba

Question

I have multiple large docx files (word 2010) which need to be split on basis of a delimiter ("///"). I tried using a macro given http://www.vbaexpress.com/forum/showthread.php?39733-Word-File-splitting-Macro-question
However it gives an error "This method or Property is not available since No Text is Selected" on the line colNotes(i).Copy (Sub SplitNotes(...)).
The macro is reproduced below:
Sub testFileSplit()
Call SplitNotes("///", "C:\Users\myPath\temp_DEL_008_000.docx")
End Sub
Sub SplitNotes(strDelim As String, strFilename As String)
Dim docNew As Document
Dim i As Long
Dim colNotes As Collection
Dim temp As Range
'get the collection of ranges
Set colNotes = fGetCollectionOfRanges(ActiveDocument, strDelim)
'see if the user wants to proceed
If MsgBox("This will split the document into " & _
colNotes.Count & _
" sections. Do you wish to proceed?", vbYesNo) = vbNo Then
Exit Sub
End If
'go through the collection of ranges
For i = 1 To colNotes.Count
'create a new document
Set docNew = Documents.Add
'copy our range
colNotes(i).Copy
'paste it in
docNew.Content.Paste
'save it
docNew.SaveAs fileName:=ThisDocument.path & "\" & strFilename & Format(i, "000"), FileFormat:=wdFormatDocument
docNew.Close
Next
End Sub
Function fGetCollectionOfRanges(oDoc As Document, strDelim As String) As Collection
Dim colReturn As Collection
Dim rngSearch As Range
Dim rngFound As Range
'initialize a new collection
Set colReturn = New Collection
'initialize our starting ranges
Set rngSearch = oDoc.Content
Set rngFound = rngSearch.Duplicate
'start our loop
Do
'search through
With rngSearch.Find
.Text = strDelim
.Execute
'if we found it... prepare to add to our collection
If .Found Then
'redefine our rngfound
rngFound.End = rngSearch.Start
'add it to our collection
colReturn.Add rngFound.Duplicate
'reset our search and found for the next
rngSearch.Collapse wdCollapseEnd
rngFound.Start = rngSearch.Start
rngSearch.End = oDoc.Content.End
Else
'if we didn't find, exit our loop
Exit Do
End If
End With
'shouldn't ever hit this... unless the delimter passed in is a VBCR
Loop Until rngSearch.Start >= ActiveDocument.Content.End
'and return our collection
Set fGetCollectionOfRanges = colReturn
End Function

For those who might be interested:
The code does work in 2010. The issue was a delimiter which was the first thing on the file...
Deleted it and it worked...
