Okay, Now I'm Stumped. HELP

The parents in my game have been married to each other, since I first created them. Somehow, however, between the time my previous iteration went bust, and I picked up a save from a much earlier time, to begin playing Cantrell Chronicles. My couple is no longer married. Say, what? I took them into CAS just now to amend the situation, realizing they would have the newlywed's thing going on, but it's better than both of them living in sin, if you will.

Sadly, what I read some complain about has now happened to me. Can't change Sims who already exist.  Really? I mean really. I have done so in the past. I'm really not wishing to go back to where I began, recently, with the family just arriving in Ondarion. (Mind you, I would keep the opening chapter.) But that's a great deal of game time. Since I'm only doing the 'Save As' with each gaming session, whether I shut down in between for whatever reason, I know I've been playing this iteration as of today for 14 days.

If you were me, and this happened in your game or something else that would bug you, what would you do?

Please, I hate to be so very needy, but this has me twisting inside --- not a good idea given my 'condition'.  GalacticGal honestly does not wish to get sick like that again! Stress is a factor.

If starting again, I do know some things I would do better. But, like I said, so much has gone on in my game, that I really, really, really don't want to go there yet again.

I just need somebody to talk me off of this virtual wall, if you will.

Please, and thank you, in advance.
