The first thing I would try is a different DXF/DWG translator - you should be able to change this in the publisher options somewhere (sorry I don't have Archicad with me at the moment to say exactly where).
Or try a smaller, simpler file with the same settings.
Maybe there is something in your file that is just taking a long time to translate to DWG.
