If it was reading the wrong version number after you installed 1.2, then you have a bigger problem with DSON Importer. You will need to take it up with DAZ 3D. Just a question, are you able to import Genesis 2? If you can't, I recommend using Genesis 2 when talking with DAZ. Unfortunately, I've heard from several people that DAZ will just say "Genesis 3 is not supported in Poser" and brush you off. Your error message and wrong version number says that your installation is not correct.
