Visual Basic 6.0 SP5, Windows 2000 Pro SP2, Power Point 2000

I designed a PPT file just with one slide, to use it as a template.

I open this presentation from VB, add it more slides and change de text frames in them; and save the presentation with another file name.

But just the last added slide in the presentation preserve the text modified by my prog. All before has this text frames blank!

Code:
Dim PPObj As PowerPoint.Application
Dim PPT As PowerPoint.Presentation

'startup a Power Point instance in background
Set PPObj = New PowerPoint.Application

'Open the presentation to use it as a template
'this presentation already has several text frame
PPObj.Presentations.Open FileName:=App.Path & "\SPS-Obras.ppt", _
                         ReadOnly:=False, Untitled:=True, WithWindow:=False

'Set the presentation to an object
Set PPT = PPObj.Presentations.Item(1)

'Call the procedure which open the database
Call OpenFoxDBC

'get data
SQL = "SELECT proy FROM cont2mil2 ORDER BY proy"

'open the recordset
If OpenRecordset(SQL, rsProg, CnFox) > 0 Then
   
   For i = 1 To rsProg.RecordCount
      rsProg.AbsolutePosition = i
     
      With PPT.Slides.Item(PPT.Slides.Count)
         .Shapes.Item(1).TextFrame.TextRange.Text = rsProg!Field1
         .Shapes.Item(2).TextFrame.TextRange.Text = rsProg!Field2
      End With
               
      'Add a new slide
      PPT.Slides.Add 1, ppLayoutBlank
   Next
End If

'Save teh presentation with another name
PPT.SaveAs App.Path & "\MyNameFile"
I trayed to add the textboxes as new objects and the result is the same.

Any idea about how to solve this problem?
