There was a thread over on DAZ about this exact problem back about when A4 first came out and I recall it had something to do with running the updater as I mentioned previously, not 100% on that cause it's been a while.

Sorry I can't post the link to the thread, DAZ and I have had a mutual parting of the ways.:biggrin:

Richard Haseltine that posts in the DAZ forum here is a mod over there and could probably get you set with the necessary info to correct this issue without having to muck about with the joint editor, though that would work.
