This problem driving crazy. I am loading tiff images into a bitmap object and passing the object to LuraTech. All working well, except for some tiff files (large files, not compressed, color, 650MB). Whe I get to pass this file to the bitmap object, i get an error: "Parameter is not valid." and Inner error: "Referenced object has a value of 'Nothing'.". The strange thing is, it does work on some machines and not on others. I couldn't find any pattern for the problem except the dot net framework release. The one that works is: 2.00.50727.0042 and my machine doesn't work with the version: 2.00.50727.1433.

Any help is appreciated. Thanks in advanced.
Private Function LoadBitmap(ByVal filename As String) As Bitmap
        Dim bitmap As Bitmap = Nothing
            ' load bitmap
            bitmap = New Bitmap(filename)     'ERROR HERE
        Catch ex As Exception
            moLog.Write("Could not load image to Bitmap. Unsupported file format.", moMail, True)
            moLog.Write(ex.ToString.ToString, moMail, True)
            Return Nothing
        End Try
