VBA Save File issue after move to Excel 2010

[Silvanus]

To any takers...

My company just recently moved to Office 2010 from 2003, and one of my macros is giving me:

Run-time error '5353':

You cannot save while the file is in use by another process. Try saving the file with a new name.

The specific part of the code copies a reworked portion of data from excel to microsoft word and saves it to a folder on my desktop.

Set AppWD = CreateObject("Word.Application")
    AppWD.Documents.Add
Workbooks("Positive Pay Upload Creator").Sheets("Compiled").Activate
Workbooks("Positive Pay Upload Creator").Sheets("Compiled").Range("A1").Select
    Range(Selection, Selection.End(xlDown)).Copy
    
' Paste the copied data into the new Word document in text format, to prevent formatting
' the data as a table.  Save the file in TextLineBreaks format to retain line breaks, but
' remove all other text formatting in the output file.
    AppWD.Selection.PasteSpecial DataType:=wdPasteText
    [COLOR=#ff0000]AppWD.ActiveDocument.SaveAs Filename:=OutputDataLocn, _
        FileFormat:=wdFormatTextLineBreaks
[/COLOR]    AppWD.ActiveDocument.Close
    AppWD.Quit

The code in red is where it breaks. I can post the entire sub procedure if it helps, but I'm hoping someone has had issues like this before. I've already enabled the Microsoft Word object library through Tools>References in VBA window.

Any help would be much appreciated, I'm totally stuck.

Thanks!
