Since it's the .obj file which is the usual keyfile, adding the morphs should have made no difference. Unfortunately, DAZ are likely to have changed the copyright date in the .obj file, and that will make the current version useless for decoding. Similar things happen from time to time when DAZ upgrades V3. The current "SAE" version has a different file to the original or the "sr1" version, but the only change is the copyright date.
