VBA Merge PDFs - Error when first and second PDF are the same

Question

Using http://khkonsulting.com/2009/03/adobe-acrobat-and-vba-an-introduction/ as a guide, I am able to successfully merge multiple pdf's together into one document using VBA (Access mdb), except when the PDF being merged to has the same name as the next PDF.
Here's my scenario.  An Access table is updated with a list of reports that need to be printed.  All of these reports are PDF's.  I loop thru this table and merge the PDF's according to an identifier, then print the group.  There are times
when there are multiple copies of the same report for an identifier.  If the PDF being merged to has the same name of the PDF being merged, an error occurs.  How can I handle this situation?
Sample data:  This identifier (ESO and Pulling) needs to merge these PDF's (Aaa.PDF) together which happen to have the same name.  Aaa.PDF is trying to merge Aaa.PDF and this throws an error.
Aaa.PDF ESO  Pulling
Aaa.PDF ESO  Pulling
This identifier merges fine despite having the same PDF twice.  But the first PDF is not named the same.  Xxx.PDF is the first PDF and merges the next two into it.  The last two
are named the same.
Xxx.PDF  916  Pulling
Bbb.PDF  916  Pulling
Bbb.PDF  916  Pulling
Code:
pdfDoc1.Open (filesToMerge(1))
numPages = pdfDoc1.GetNumPages()
Set pdfDoc2 = CreateObject("AcroExch.PDDoc")
Dim i As Integer
For i = 2 To intNbr - 1
pdfDoc2.Open (filesToMerge(i))
If pdfDoc1.InsertPages(numPages - 1, pdfDoc2, 0, pdfDoc2.GetNumPages(), True) = False Then
MsgBox "Cannot insert pages"
End If
pdfDoc2.Close
Next i
If pdfDoc1.Save(PDSaveFull, "C:\....\ReportPacket__" & Trim(CStr(intReportCount)) & "__" & ... & ".pdf") = False Then
MsgBox "Cannot save the modified document"
End If
pdfDoc1.Close
The pdfDoc1.InsertPages command fails, displays "Cannot insert pages", then displays "Method 'Close' of object 'CAccroPDDoc' failed.
Thanks for any help or advice.

Hi
As far as I know, Access didn't provide such method. But I think you are able to achieve this goal through some 3rd party PDF component
Hope this will help you.
