Good news and bad news:
Good news: I found out what the problem is!

hehe. It seems, and I could be wrong, as usual with these mysterious applications, that DAZ doesn't add ERC codes on the fly, unlike Poser (due to a debug message right at the line of the first master parameter coding during the injection). So I'm going to have to make some kind of script, similar to the python job Ken and I did for the older Poser versions, but not only add groups and channels, but now also ERC coding to the V4... O.o ... with DAZ scripting. Now I've seen that DAZ scripting isn't entirely documented, but I hope that was an old post, cuz otherwise ken and I are in trouble... and you. In any case, people, this might take a while... :(
Other option is to still try the ExP System. But there is a bug that doesn't explain itself, and DAZ users will be limited to a new V4.
Thank you for all your tips and comments and help. Keep ya'll posted!
