A but stuck on some Japanese?

I am trying to learn Japanese via Rosetta Stone, although I have only downloaded the first section before I lay for the package. And I am stuck already!
It has taken me three nights to learn:
Man - Otokonoto
Woman - Onanoko
Boy/Girl
And then the woman is running, the man is eating, the girl is drinking, the boy is swimming etc
Now I have got to a different section and it is now referring to a woman and a man as something else and not as I learned before,
I can't remember exactly what it's saying but it's something like Kanojowa and Konowa.
Can someone explain this to me please as I am rather stuck!

Thanks
