That worked!! I was able to load her in CAS. No green face. However, I had to change the skin tone, due to her skin being black - as if the skin didn't install correctly or was corrupted some how.
That's an easy fix, if you ever run into that yourself.
1. Take the Sim back into Create a Sim. (Your Sim may be entirely grey/black.)
2. Under the Basic Tab, change the Sim's skin tone color to it's original color. - For example: My Sim had a light skin tone, so I choose yellow. (Now you will see the body/head align a little better.)
3. Click on the Swimwear tab to get the skin tone back to normal.
Then I clicked on the options button under their photo to save them to the Simbin. So I had a saved version of the fixed Sim. And went to play them.
I do notice that she doesn't (?) have a formal outfit. I'm assuming that might be custom content or something from the store? I don't have any store content installed at the moment. As I'm using a new Sims 3 folder.

Note: She doesn't have any traits. She came that way in her .sim file.
