I've learned that if you want the full benefits of a new version you must delete the families you have and create new ones. For some reason, the new version seems to cause odd problems (only sometimes) with established families. So, I delete the old and create new. Eventually LDW won't need to make any new versions (I don't think they need anymore now as my game runs beautifully now, thank you LDW!) and then you won't need to start new families anymore.
