Could not complete operation on some files - vb.net

Question

The below code basically takes a directory, copies it the zips it up. This has worked perfectly for me for the last 6 months
Dim tempMail As String = Temp
Dim startpath As String = tempMail & tvProgress.SelectedNode.FullPath
Dim outMail As String = "c:\LTEMP\"
Dim fileout As String = outMail & tvProgress.SelectedNode.Text
Dim tempfolder As String = "c:\LTEMP" & "\" & tvProgress.SelectedNode.FullPath
Dim Reality As String = "\Reality Stock Report"
Dim enUK As New CultureInfo("en-GB")
Try
Dim x As Integer
Dim q As Integer
Dim inMail As String = FileStr
If CheckInternet() = False Then
MessageBox.Show("No internet connection is detected!" & vbNewLine & vbNewLine & "This job will still be added to completed but you will need to connect to the internet to complete sending this file to CIS", "Internet Connection Check", MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1)
End If
If tvProgress.SelectedNode.Parent.Text = "Archive" Then Call INIDate()
Dim Datey As String = Nothing
If tvProgress.SelectedNode.Parent.Text <> "Archive" Then
Datey = Date.ParseExact(Convert.ToDateTime(tvProgress.SelectedNode.Parent.Text), "dd/MM/yy", enUK)
Else
For q = 0 To UBound(INIdet)
If tvProgress.SelectedNode.Parent.Text = "Archive" Then Datey = INIdet(q).iDate
Next
End If
If My.Computer.FileSystem.FileExists(startpath & Reality & ".docx") Then
Call Word2Pdf(startpath & Reality & ".docx", startpath & Reality & ".pdf")
End If
System.Threading.Thread.Sleep(150)
For x = 0 To UBound(AllDetails)
If AllDetails(x).uName & " - " & AllDetails(x).uCode & " - " & AllDetails(x).uOps = tvProgress.SelectedNode.Text Then
If AllDetails(x).uPlan <> Datey Then
DateCh.Show()
Exit Sub
End If
End If
If AllDetails(x).uName & " - " & AllDetails(x).uCode & " - " & AllDetails(x).uOps & " - " & AllDetails(x).uPlan = tvProgress.SelectedNode.Text & " - " & Datey Then
Application.DoEvents()
My.Computer.FileSystem.CopyDirectory(startpath, tempfolder, True)
Directory.CreateDirectory(fileout & "\")
With tempfolder
For Each xDir As String In Directory.GetFiles(tempfolder)
If Not ((UCase(Path.GetDirectoryName(xDir)).Contains("BACKUP")) Or (UCase(Path.GetDirectoryName(xDir)).Contains("BARS")) Or (UCase(Path.GetDirectoryName(xDir)).Contains("TCMS"))) Then

I've recently added the following bit of code which calls a routine that converst a docx file to a pdf (works fine on its own)
If My.Computer.FileSystem.FileExists(startpath & Reality & ".docx") Then
Call Word2Pdf(startpath & Reality & ".docx", startpath & Reality & ".pdf")
End If
System.Threading.Thread.Sleep(150)
The called sub
Public Sub Word2Pdf(ByVal infile As String, ByVal outfile As String)
Dim wordApp As Word.Application = Nothing
Try
wordApp = New Word.Application()
wordApp.Documents.Open(infile)
wordApp.ActiveDocument.ExportAsFixedFormat(outfile, Word.WdExportFormat.wdExportFormatPDF)
Finally
If wordApp IsNot Nothing Then
wordApp.Quit()
End If
End Try
End Sub
Now when the criteria is met to call the above sub I'm getting the Could not complete operation on some files error. When I check the directory the PDF has been created but its not then completing the rest of the zip and copy routine.
Any ideas??

WordApp probably has one of the files locked. Check to make sure WordApp has finished execution before you continue. The Sleep(150) is apparently not long enough.
