SDF Loader for AutoCAD 2010 version of drawing

[wesbird]

HI, 

  I'm migration my tool of SDF Loader to work with AutoCAD 2010. I got this error message, 

    Error : Unable to load data. Please check the input filename and format.

  Does SDF Loader 6.5 sp1 work with AutoCAD 2010 version of drawing?

  if not, is there any tool I can use to generate SDF 2 file?

  if yes, is there any API so I can programming with it? VB6, .Net (VB.Net or C#), AutoLISP or ObjectARX ?

Thank you,

Wes

The sdf loader sp1 works with 2007/2008/2009 dwg version. For 2010 you need to save the dwg  in the previous version.
