If you do not have any objects in your drawing that are specific to versions above 9, then a DXFOUT or SaveAs may give you a dxf file that your other software can use. For instance if all you have are 2D lines and circles then I'm almost sure it would work. Give it a try - you have nothing to lose! If you have already tried it and it did not work, try a google search for translators or as a last resort, edit the dxf file yourself..
