Error when opening HPGL files

[ngoell]

Hi,

I am using Cad Import.NET and whenever I try to open a HPGL file with the supplied viewer application I get the following error:

Unable to cast object of type 'CADImport.CADBlock' to type 'CADImport.CADTable'.

************** Exception Text **************
System.InvalidCastException: Unable to cast object of type 'CADImport.CADBlock' to type 'CADImport.CADTable'.

at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)


The exception is thrown when trying to instantiate a new HPGLImage() class with the default constructor!!!
Please, advise me on how to successfully display HPGL images.
