UPDATE: It's not the Immortal status you need. I just checked in with the MCCC Help Thread. This is what's required. Go through the computer and select MC Tuner>Change Interaction Behavior> Allow Emotional Deaths and select disable. That way you don't have to worry about your Sims' family growing up without them. :)
I am very happy to report that after replacing Origin not once, but twice (had to do it again today) my game is repaired with all pack installed. Yay! Erik has made an additional §15000 and his identical twin nephews are now toddlers. Yay. I have disabled emotional deaths, but am very glad to have experienced them, almost five in total. :open_mouth: There is such a thing as enough is too much. ;)
My heartfelt thanks to all of you who responded lending your support and advice. Going back in game, now. :)
