Dear Mr. Rompelstilchen,
Could you please post exactly what version of 3DxSoftware you are using and your operating system and Blender version?
The current drivers are for the current versions of applications. There is a pre-2007 AutoCAD plug-in. It is a legacy plug-in and is not supported but is still available on our web site. I will included instructions for downloading it at the end of this post.
Sincerely,
Bryan G.
