Found the David head and body morphs among all the stuff I've purchased and reinstalled them.  Now there is a David folder in the !DAZ folder.  I then tried injecting the Lionel character into my new M3 character and it worked!

I also reinstalled and tried loading all the M4++ onto M4 and it worked!  A couple of years ago I couldn't get it to initalize.  I was even working with support at DAZ and they couldn't figure out why it wouldn't initialize.  But it's ok now.

Thanks much for your patience.
