ePermanentlyErased - PlotSettings

Hi All,

I am trying to retrieve page setups from our plot.dwt files by accessing the database through ReadDwgFile (each project has its own plot.dwt). For some of the files it works, but others, I get an ePermanentlyErased exception when I try to cast the oPSID to PlotSettings.

My question is:
How can I find out what is erased? The oPSID or the PlotSettings?

{code}
Public Function GetPlotSettings(ByVal FileName As String) As List(Of Batch.ImportPlotSettting)
Dim ListOfPlotSettings As New List(Of ImportPlotSettting)
Dim db As New DatabaseServices.Database
db.ReadDwgFile(FileName, DatabaseServices.FileOpenMode.OpenForReadAndAllShare, False, Nothing)
Using tr As Transaction = db.TransactionManager.StartTransaction

Try
Dim oPSID As ObjectId = db.PlotSettingsDictionaryId
Dim oPSDict As DBDictionary = CType(tr.GetObject(oPSID, OpenMode.ForWrite, False, False), DBDictionary)
Dim oDictionaryEntry As DictionaryEntry
Dim oPSV As PlotSettingsValidator = PlotSettingsValidator.Current

Dim oPlotConfig As PlotConfig
Dim oPlotSettings As PlotSettings

For i As Integer = 0 To PlotConfigManager.Devices.Count - 1
Try
PlotConfigManager.SetCurrentConfig(PlotConfigManager.Devices(i).DeviceName)
oPlotConfig = PlotConfigManager.CurrentConfig
Exit For
Catch ex As Exception

End Try
Next

Dim oPlotInfo As PlotInfo = New PlotInfo()

For Each oDictionaryEntry In oPSDict
oPSID = oDictionaryEntry.Value

''''ePermanentlyErased''''
oPlotSettings = CType(tr.GetObject(oPSID, OpenMode.ForWrite, False, False), PlotSettings)
''''ePermanentlyErased''''

'' Other code here
Next
Catch ex As Exception
Application.ShowAlertDialog(ex.Message)
Finally
End Try
End Using
{code}

Is someone out there familiar with this and able to give some pointers or advice?

Thanks

Brent
